>> reporter: police say nichols was pulled over for allege reckless driving on the night of january 7th. according to the district attorney, after an initial altercation with police, pepper spray was deployed. nichols then fleeing. he was confronted again, resulting in serious injuries. memphis police saying nichols complained of having a shortness of breath, at which time an ambulance was called to the scene. the 29-year-old critically injured, died 3 days later. the family commissioning an independent autopsy. their attorney stating, preliminary findings show nichols suffered extensive bleeding caused by severe beating. at this time, that autopsy has not been publicly disclosed, and abc news has not seen it. two memphis fire department personnel involved in treating nichols were, quote, relieved of duty while an internal investigation is being conducted. those five officers all part of the department's strict crime

unit known as "scorpion" fired after an internal investigation concluded they "violated multiple department policies including excessive use of force, duty to intervene, and duty to render aid." >> this is not just a professional failing. this is a failing of basic humanity toward another individual. this incident was heinous, reckless, and inhumane. >> reporter: the director of the tennessee bureau of investigation speaking today. >> frankly, i'm shocked. i'm sickened by what i saw. i've seen the video. you will too. in a word, it's absolutely appalling. >> reporter: attorneys for two of the former officers, desmond mills jr. and emmett marden, saying their clients intend to plead not guilty. >> no one out there that night intended for tyre nichols to die. >> our thanks to elwyn. we turn to cryptocurrency. just a year ago, several

a-listers were lining up to urge investors to jump in. a lot has changed since then and for many the risk has far outwade the reward. here's abc's rebecca jarvis. >> reporter: 2022 was quite the year for crypto. >> cryptocurrencies went on a wild ride today -- >> promising huge returns fast if you invest in cryptocurrency -- >> reporter: it started with super bowl ads. >> a trade, are you sure? >> not a trade, trade. a trade in crypto. >> reporter: crypto logos plastered on multiple arenas. the rich and famous entering the conversation. >> fortune favors the brave. >> reporter: it's seemed like everywhere you turned, someone or something was trying to get you to buy cryptocurrency. >> the safe and easy way to get into crypto. >> yeah, i don't think so. and i'm never wrong about this stuff, never. >> reporter: it turns out he wasn't. >> bitcoin and other cryptocurrencies have taken a

nosedive. >> about $8 billion vanished. >> now they're crashing. >> reporter: you may have heard about ftx, but it isn't the only crypto company that's in hot water for leaving hundreds of thousands, maybe even millions of customers, in a really bad financial spot. >> i have to accept that $107,552 is a lot of money to lose. >> it's embarrassing, to admit in front of other people that you lost money in a place you thought was a credible place. >> the united states government needs to get off their [ bleep ] and protect consumers. >> how was your day at school, babe? >> good. >> three kids? >> three. >> all under the age of 6? >> yes. >> you have your hands full. >> totally. >> but you're trying to give them a better future.

>> absolutely. >> reporter: curt dell has lived in southern california his whole life. he works in alcohol sales. his wife, victoria, is a nurse practitioner. >> that's all i think about when we talk about it, such -- it robbed them of so much potential. so it's -- it's just -- it's such a bad situation. >> this is where you're trading bitcoin? >> it's where i used to. >> reporter: the bad situation he's talking about, more than $200,000 worth of bitcoin he can't access in a crypto app called celsius. think of celsius like a bank, but for cryptocurrency. it all began in 2017 when curt bought about $30,000 worth of bitcoin. at the time he invested, one bitcoin was worth between $3,000 and $4,000. over the next few years, he gradually bought more, riding the crypto frenzy as the value

of one bitcoin soared to nearly $70,000 in late 2021. >> when it went to almost $70,000, she was kind of saying, hey, maybe we should sell it. and i was adamantly against it. >> reporter: his account balance at its height was almost $1 million. but of course, big rewards came with big risks. in the spring of 2022, a major crash. the total value of cryptocurrencies, everything from bitcoin to ethereum to dogecoin and lunis tearra, collapsed from almost $3 trillion in 2021 to less than $1 trillion in 2022. over $2 trillion in value wiped out in a year. >> i've been calling 2022 the year of crypto carnage. >> it started with a huge amount of intense optimism that was quickly punctured and replaced by just total catastrophe.

>> reporter: the collapse shook the industry and brought a number of crypto companies down with it. celsius was one of the them. >> what the crash did was prompt a kind of run on the bank. people panicked. they thought that their cryptocurrencies were in danger, and they moved to withdraw everything that they deposited in celsius. and that's what kind of exposed the kind of shaky foundations of the whole company. >> reporter: on june 12th of 2022, celsius froze customer withdrawals. one month later, the company filed for bankruptcy, saying it owed customers $4.7 billion. so how much money did you think you had when those withdrawals were suspended? >> it was in the neighborhood of $350,000. >> what would that money have meant to your life? >> everything. my kids' education. my mortgage. my student loans. my wife's student loans. i'd even got her involved in it,

which was another part that made the situation so terrible. she invested some of her money into it too. >> it's sad that, you know, i feel like we were violated and made victims. i was raised to be a hard worker, and so to have a company potentially take away our life's -- not life's savings but a very big portion of it. >> crypto kind of rose out of the 2008 financial crisis. that whole catastrophe was an example of the failures of the centralized financial system. and it helped inspire this movement to create a parallel financial system that didn't rely on the types of institutions whose bad behavior had caused a lot of people to suffer. >> reporter: but in recent years, a number of companies have popped up that act kind of

like crypto banks. they're places like celsius that promise big returns for storing your cryptocurrency in a kind of high-yield savings account. and a number of those companies have moved or teased moves to miami. it's a city that's completely embraced crypto. >> these kinds of technologies can revolutionize the way we experience the world. they revolutionize the way we do financial transactions. >> reporter: here, you can find bitcoin atms on multiple blocks. there's a crypto school in winwood. enthusiasts gather for crypto happy hours. you can pay with bitcoin in nightclubs. >> do you own any crypto? >> i do. i get my salary in bitcoin. >> are you living off of your bitcoin? >> no, no, no. >> okay, so your salary is just supplemental? >> correct.

>> why would anybody put money into a cryptocurrency, given what we've seen? >> you know, those are two different questions. i think the first question is, it's exciting to a lot of developers and lot of engineers, which are the ones that propel innovation. the second question is, why should anybody invest in it? i don't like to give investment advice. >> what are the chances you'll get this money back? >> i'd like to stay optimistic and think that i'll get a -- at least a significant portion of it back. when i watch the court case and i'm highly involved it in, i couldn't tell you that with certainly. i don't think anybody really knows. >> the celsius bankruptcy case is promising to be long and drawn out, as bankruptcy cases often are. >> reporter: there was initially hope. curt and others thought they could get some relief. but the guy who was potentially going to bail out celsius and its customers by bidding on its

assets, well -- he's a bit tied up at the moment. >> people were calling him the white knight of crypto because he was offering to buy these the assets of a number of these distressed lenders to, as he put it, make sure that retail investors don't get hurt. >> he went from this kind of super-rich crypto wunderkind to this crypto king who was going to save the whole economy. >> our thanks to rebecca. celsius network is still going through the bankruptcy process and for now it's too early to know whether customers like curt will get any of their cryptocurrency back. for more on this crypto craze check out "impact on nightline" streaming now on hulu, new episodes drop every thursday. the smallest spot of a dot. how a new children's book by one of our own is celebrating our differences while sharing an

♪ you know, the human project may be complicated, but it reveals a simple truth. that's the focus of a new children's book by our colleague, who's also a best-selling author. i sat down with the anchor of "abc news live" linsey davis. so glad you're here on that side of the desk. >> i'm so happy to share the desk with you. >> i've long admired your work as a journalist. you are such a fabulous children's author as well. this is called "the smallest

spot of a dot." your fifth book. we're different, the big ways s- we're the same." what's this book about? >> so i've always had this fascination with the first phase of the human genome project, which that was 13 years long, it involved thousands of researchers from around the world. it was such a comprehensive undertaking in the science world. basically what they found, because they were setting out to map the blueprint of human dna. what they found is that we're 99.9% alike when it comes to the sequencing of the dna. so it's just .1% that determines our hair color, our blood type, anything that makes us unique. and so i was talking to a friend of mine about, how would we make something so complex simplified, that even the youngest among us, somebody 4 years old, would be able to understand this? we came up with the idea of dots. the molecules, it's 3.1 billion monthly sules in the dna, right? in the book, i call it the

"me/my/mine" dot, anything that makes us unique. so it's both celebrating the differences, also embracing the way that we're so the same. >> we talk about how representation matters. obviously the kids in this book represent a very diverse background. why is that important to you? >> you know, so thrilled to be working with lucy fleming again, the illustrator. my goal in all my books, i feel like i will have successfully achieved what i was setting out for if any child that picks up the book is able to point to a child, a character, and say "that looks like me." "she looks like me." "he looks like i do." we even have this inn this book a little girl in a wheelchair. i feel it's so important to bring everybody into the tent. that's something in recent years has been picking up, but even prior to george floyd there was such a lack. you'd either find a book that typically had a white protagonist, other than that, just black characters or just a

certain kind of character. in these books, i really feel like in any given spread you're going to see somebody who represents every race. >> we know you as a hard-hitting journalist, in your political analysis. what made you get interested in doing a series of children's books? >> you know, i've always considered myself to be a storyteller. >> sure. >> what we do every day, right? it's often the goom, gloom, mayhem, murder, missing. shortly after i had my son, i was reading children's books to him from the time he was an infant. i first and foremost thought, i'm a storyteller, i'd love to write books. then when i really started to see the lack of books with children who look like my son, rather than grum el bell and complain i felt, let me be part of the solution and start creating books with characters that not only look like him, but all different kinds of children. >> and so what is the main message for this particular book? and if there's an overarching theme, what would it be? >> embracing each other.

it's self-love and love for others. i think it's about empathy, about teaching that at an early age. i really am trying to instill that message in kids. >> i love that you took this incredibly complex concept of the human genome project and really made it accessible, not just to the kids but to the parents who are reading it to the kids. >> as a mother who was at one time -- now my son can read on his own, but when i was doing the reading, i always wanted, first of all, something that kind of entertained me while i'm reading these books ad nauseam again and again. also for there to be a little bit of a takeaway, a sugar-coated medicine for the kids. >> the medicine tastes great. thanks so much, linsey, for joining us. i appreciate it. >> thanks, juju. >> good luck. it's a bestseller. >> already, thank you. >> fantastic. up next, an historic surgery. twin sisters conjoined at birth. and the medical team that stepped up to change their lives. >> you have two babies on two separate beds.
