we come to germany. in the order of our license to work as a swimming instructor. for an hour to children to disrupt. what's your story take course share it on informal grinstein. i haven't invested in any yet myself i should cryptocurrency is playing an increasingly important role in the economy companies like tesla accept a bad call as payment even some fund managers recommend investing in digital assets but how do they work what are their implications for everyday life cryptocurrency

other worth the ride our topic today and made welcome. it was one of the hottest i.p.o.'s of the year driven by the cryptocurrency bull market call in bass made a huge splash on wall street with many industry hopes pinned on the u.s. as biggest digital currency trading platform and bitcoin the world's most popular crypto currency seems unstoppable it's just reclaimed the $50000.00 mark recouping some of its losses following washington's plan to raise capital gains taxes for wealthy investors now that was a tiny set back but then bitcoin bounced back again are cryptic currencies indestructible or just a fun gamble for those with money to burn mr schmidt to went to find out. i believe him because in the hope it will become the most important currency in the rule nothing is more real than. ok we weren't being entirely serious there

but belief and trust do play a role in that client's viability let's consider the process. of i thing the coin is revolutionary so there is no fear of inflation because there's a limit only $21000000.00 records are allowed to be mined and people have a transparent process the whole time and it's safe and secure and it's cool i think . well most big corn is still sort of your chill for me it doesn't have any i'm barely you basically it's all fair show and if you think it's like bubble yes admittedly in the 1st years after its launch in 2000 his value increased only gradually and its image was spent think about how many imbued quiet strength actions were used for illegal for example drugs where all of the criminals use bit choir but in the big world something is changing countries like

germany do force because it uses to verify themselves before they enter the big chord world so it's not that anonymous as it used to be over the next few years confidence grew as bitcoin's technology proves stable and the price even hit $100.00 euro's but a crash was just around the corner at some point price to cryptocurrency between stolen several $1000000.00 europe's worth was last year it's also not regulated but think about it if someone would steal your money take a look at your crouch some points were already stolen in the post where is the guarantee that it will happen to your beat clients actually the big con infrastructure has never been hacked so it's safe and we're talking about 12 years and some big guns have been stolen i agree but the reason is those people do not

care to have it in a safe place interest must prove that boosted after a few celebrities support the venture backed arrest could read by kanye west and the think of force brothers. and it was the big question. first. bitcoin isn't good for everyday purchases let's listen to my expert. then if that ever happens it's still decades away hunger on the run to cryptocurrency consulting firm he has been following bitcoin for years. obviously there's the volatility of the coin to consider which discourages people from spending it. and there's always the question why should i spend money today when it may be worth more tomorrow it is time to get some help and some support is going pretty well already then please leave our managers of fund worth billions and he advises investing in bitcoin. i suspect

that acceptance will grow in the next few years partly driven by greed because the prices are clearly going up and up that's when people say now i want in on this but also because it's simply becoming socially acceptable there was a months long period where the price of big gone soared due to investors discovering its potential as a financial investment. in terms of bitcoin i'm very much in a speculative realm i see it as more of a security than a currency. but behind i'm on for a bit coin has also led to massive energy consumption to keep the system going to look at the server in china. one bitcoin transaction releases as much to you too as $100000.00 credit card payments. list think about climate change and you said here are eco friendly but if you think

about how much an artist consumptive to produce to keep the whole system of bitcoin alive it can be compared with the whole country oh you've got me ok that's maybe your best argument most of the energy that is needed for the corn world is concerned in china about 65 percent and they are shutting down companies. that work with coal power and they would like to have war companies using hydro power and would its value continue to rise. could mean big point is limited in quantity there's a certain cap on the number of bitcoins that can ever be produced but the demand for bitcoin hasn't been met there are a lot of people who have not even invested in it yet it's likely big corn prices will continue to rise significantly over the next few years as more people become familiar with because. so now have i been able to convince my colleague of

merits. not recognized by so many countries i think. it's more we get. more here what is it about this and it 1st. it's more. and it's more. criminal. the problem was the climate change. then i don't mind. but. i believe. we do not have to believe in the old common currency our parents did it so we have a new. super cool currency that's ok.

i guess the last word and trip to currencies has yet to be spoken but in the meantime you can try your luck by investing in them bitcoin if area near well they can all be loaded onto your smartphone in exchange for local currency and you can use them to buy many things online there are thousands of such digital currency switch makes it hard to see the wood for the trees so here's a look at how they actually work. 100. almost any.

international bank. and 2550. banks and. that's why i.

want. so what can you buy with that perhaps a piece of hot forget about buying a traditional painting or sculpture something that you can perhaps hand up and hold on the wall or display in your garden come on it is so yesterday in today's online well it's investing in artists also ditch it till welcome to the world of and if t. s. that's long fungible tokens which are also stored via block chains and of course you can use crypto currencies to buy them now is this the future of the world or just

a passing fad if you decide. i'm in any city in the mood for perhaps the most famous painting in the wilds worth around $700000000.00. and this is a mona lisa of the digital world a 10 2nd clip sold for 6600000 that anyone can watch online the cap mean you've seen before downloaded millions of times sold for 600000 dollars this image sold to 0.5 either about $650.00 at the time just a short time later it was worth another $1000.00 so think that this song well welcome to the world of n f t's digital objects twitter cryptocurrency. and oh well even christie's has now joined the game for seeing the 1st of the n.f.c. up football action. but hold on why would anyone pay that sum for an account mean

that they can share and download for free is it over scouting or is just a future of the world and if keystones been on fungible to call $900.00 full when something is known fungible it means it's not easily interchangeable because it's unique or scads take a dollar note if you have a $1.00 and if you don't mind trading it with someone else's $1.00 note makes no difference. the mona lisa on the other hand is the make. a piece of digital all these fungible it's not unique or scan yes because it can be downloaded and copied to infinity. but when you create a t.v. for it a process called tonight single minting it becomes just the trace of legal thing to take and unique. how to put it simply and n.f.c. contains a specific set of data plus there's information stored on the token about you created the content for how much it was sold and the owner is that way the token represents a certificate of ownership. technology ensures that all that info is on changeable

and for. i prefer so while the digital object may still be all over the internet buying the f.t. by the city if we can take ownership for it. so. based things. need energy market right now it's really nice tara think a lot of people who are buying. really early on have a lot of they don't want to cash it out. just the way. i do think that the energy market in general has a lot more and. more are so trading cards the market may be small but in the digital not wild something and if decent revolutionary tool allowing digital artists to authenticate their work and easily and in a foolproof way for the 1st time i don't anticipate is a little when he announced the actual artwork itself even the physical painting

isn't necessarily where value is held so you may have the most valuable out work in the world who how being able to a friend's case it. can potentially have a value of 0 or some collectors may value it but generally speaking you're not going to be able to get it into a tree house likes of a b.s. or something like the technology also allows artists to collect a percentage of their revenue every time that plug is something that's not the case in the traditional markets and they can sell their are more direct. any artist with a computer and photoshop and a dream can get on and start making money from their own and start benefiting from it and it really doesn't power the individual and empower the masses to get involved with the art world in a way that has never really been done before when it comes to the n.f.t. market as a whole many involved in watching it caution them they want the potential of the market and the high environmental costs of any teams because for now that creation

and transactions consume a lot. amounts of energy. some predict the sky high sums currently paid for certain items already waiting to. receive people understand the concept of earning their true assets more and more i think we'll just see this grow as a generation of people coming generation is going to grow up and they're going to be much more interested in buying something staged for than they are buying something physical tees are still pretty nice for collectors but they could become a global trend and gain wider appeal as an investor. now moving on to perhaps more pressing issues what could a covert 900 test have to do with crypto currency or the verification off a vaccination certificate quite a lot actually there are

a lot of instances where this technology that seems abstract to the average consumer is already at play in our everyday life so take a look. but they begins as it does for many of us in germany with a coronavirus test. the pandemic is part of everyday life you need to take a test to go shopping see family or go to work if it's negative you have a sudden if temporary sense of freedom here it is the cover test result negative fortunately but is such a certificate really trustworthy. can such documents be faked yes they can a quick search online soon reveals there's a flourishing market for fake negative test results it's not all that surprising it's easy to scan a test report tweak it with image editing software such as photoshop printed out and write in any name you like another photoshop expert but that even i can do. you

purchase a start up in cologne devoted to ensuring data security and integrity its c.e.o. stefano la. i sent you an email can you open it and we start with a little surprise. you say we're negative test results back you could you make it secure absolute going to salute that's why we've developed our technology in a case like this we would attach a q.r. code to the result is a digital seal of off intensity. you can think of it as a kind of digital notarization as soon as the test comes out of the machine a microsoft ticket is generated and digitally signed by the lab. if you then present the results somewhere else it can all be checked and verified. hubert's has worked on the certification of test results in the healthcare sector now it's developing a fake proof official german vaccination certificate in corporations and i.b.m.

using technology from the foundation cryptocurrency developer based on the in. your to is a readily accessible public block chain that fulfills all required. it's been built for precisely the kind of things we do namely the internet of things measurement data and such rather than transactions involving value. it's about the persistence of data. that means the availability of unchanged data over a long period of time dominic she is a co-founder of field and develop this technology i give him a little surprised. very convincing negative. of course he was joking so we both take another at that coronavirus test and just like with block change we verify each other's result some negative that's been confirmed by both parties trust has

been established. that. the problem is that i can't trust the systems currently in place. i can't trust this piece of paper because the signature could have been faked. i can't verify that the text is legitimate. the same problem exists in the virtual world. the foundation's mission is to make data and the digital trust with. any health should enable the secure sharing of medical data that was 1st authentic aided by responsible authority or doctor encryption ensures that they can't be tampered with control of the access would be in the hands of the individual. however this only works if the data is actually authentic. as we've seen with photoshop you can easily change a test report on paper. you can also manipulate data in the virtual world.

change a couple of bytes and all of a sudden you have a negative test result even though you in fact tested positive. the aim of our technology is to encrypt and secure data so it can't be changed. for and. authenticating and securing sensitive data doesn't sound very exciting but it's incredibly important in health care and in the burgeoning internet of things. now own encrypted currency is turning many people's lives upside down just imagine you own hundreds of millions of dollars worth of bitcoin but then you lose the password to access your account you try everything but every password you enter is wrong eventually axes will be denied for good your money gong sounds like a film script but it really happened and to at insult to injury to a computer programmer in our last report for today we share the stories off to coin

onerous and how bitcoin changed their lifes. i got to a point where i was at my absolute and. and i hit rock bottom. and all that place the euro and other currencies it's the sound choice and stay away from the other crap for now. the value of bitcoin has been rising rapidly for months. and bitcoins for a long time have made a lot of money techies entrepreneurs invest as they're being taken most seriously then i'm at a high end here it's the same the owner of the legendary bitcoin 77 cents 2011 you've been able to pay for beggars and be a hero with a big calling. i'm your 53 years old and i'm the one who turned this bar into a big coin holding up. our standing in front of the 1st venue in the world where

bitcoin has accepted. the bar got a certain amount of fame and cult status. but coined and when i discovered bitcoin known among bitcoin is as the bitcoin moment. my god it's finally here. it's time that used to be now we've got digital cash. logical to say ok we want to accept this payment here corner put up a sign we except big point here. back then no one knew what it was there were maybe one or 2 berliners online also interested so i met up with one of them here then he paid for his burger and beer and bitcoin and wow that was an incredible feeling. we didn't realize at the time but it was also an historic moment because it was the 1st time that i knew what i'd used to pay for something physical and a bricks and mortar store. became a meeting place for

a big coin founds from. another well known 1st generation. he lives in the u.s. but his story is tragic he lost the past but to his digital big clean one it's and can they learn to access usenet less of me and. it was it was small and i didn't know what to do but as a developer and a tech person of course i thought about ways to restore the data there are all kinds of recovery options. i spent the next 2 to 3 weeks 24 hours a day trying out different possibilities even hard disk recovery in the end i realized it probably wasn't going to work. now he has just 2 more possible but attempts 8 of already being used it's about 7002 big coins. just doesn't know who decisions that are so there's still a chance that i'll get access just have to wait and see. but i'm trying not to get

my hopes up too much so that i'm not devastated later if it doesn't work. i don't think it was random. the fact that i had such a low point gave me a lot of motivation and clarity about what i want to achieve in life. i take every opportunity to talk about bitcoin you know about financial access to let more people participate in the financial system. i'm grateful for this platform . platform. yeah it doesn't reveal whether he still ends bitcoin but he says that me and demond is a big point ex-pat that young. guys who drive lamborghinis that's a narrative that i find completely uninteresting to me well that means having enough and that doesn't have to be a cost a little not to be allowed for gaining numbers i don't need to have more than others what's so important with bitcoin it's not that individuals get rich but that

everyone becomes better off in a year i. don't know dozens owns i own best. distance cased. because i mean as a new system that's what he believes and. i'm for drawing isn't personal responsibility is a huge topic which many understandably also shy away from. because they say a banker has always looked after my money and i was insured and i was supposed to do it myself. and i can understand why people say that stupid under the law to be middle other people like me think that some toxic is something you should deal with . quite simply that the sooner the better when you from that if. and that's all for this hopefully not too cryptic cryptocurrency edition of made why don't forget of course you can always comment on all of our stories on one of our social media channels we always look forward to hearing from you in the

meantime from me and the team in berlin thanks for watching stay safe.
