And so what that means is that people, you know, they just print it, devalue it, and you cant count on anything like, i dont know how many dollars are going to print next year, but i know exactly how many big ones are going to be issued. So can we call that currency, should we call it . Cant say its, its the best currency the just on the planet.

But we kept at it. Yeah. Why . I dont know. Its just something we believe in. We just believe that crypto is the future. Do you worry at all about the security of it or the whether its a scam in any way. I worry more about the dollar than i do bitcoin. I do believe its going to be the currency of the world, but if it is bit going, has a long way to go. Few american seem to be spending it for most is just another investment. But where does bitcoin come from anyway . Im heading into the pennsylvania countryside to find out when i get their future finance as a little money than id imagined. I, jeff, i may say nicely. Or what is that noise . What youre hearing are the klein miners, the, the big one is in the next one liners. You can see all the little fans in there. Theres a little computer on each one of those fans. Jeff campbell is the lead engineer stronghold Digital Mining. It has 12000 specialized computer processes, are looking for 200. This is a long number and everybody in the world is working on the same equation. Theyre all trying to find the same number. And if you get it, if you get it, you get 6. 25, that point right now, and how often do you get it every time that its somebody on in the world finds that number is high tech lottery to function . Mine is race to verify the newest transactions made everywhere on the big coin network. The winner is rewarded in bitcoin. Its an entirely digital process, and it used to be done by amazon enthusiasts on home computers. But these days, its big business, and the u. S. Does more of it than anywhere else. Worldwide, were going through more combinations of numbers and there are grains of sand on the earth. So you can say its profitable if you can find that grain as those profits are putting in bigger and bigger, operates as a 21st century gold rush. But heres the catch. Bitcoin was designed on a system called proof of work. The more processes get thrown at it, the heart of the algorithms become, the harder the algorithms become more computers and needed. Its an energy guzzling arms race. And this is how strong holes operation gets his power, their own dedicated power station. It burns fossil fuels, coal waste, with all the Greenhouse Gas emissions that entails stronghold ceo greg bill takes me into the hissing, roaring heart of the beast. Vocals me the oldest kind of brut industrial power, is just going to make something that you cant even touch it. Its a Digital Currency that kind of plates around and then in the spare it is after the old world industrial mates near will finance. But whats the environmental cost of all this Cambridge University says, bitcoin pumps out as much c o 2. 00 per year as a country like check republic and consume as much energy as the whole of highlands. Then greg tells me something astounding when we started the project. 4 or 5 years ago, the mining economics for bitcoin were really enough to support the plant. Thankfully the state of pennsylvania in a, in a bipartisan way, modified the rules a bit to allow us to earn more of a, whats called the Renewable Energy credit. And that isnt that plus higher power prices was a port is running today. So pennsylvania, not only coals coal waste, an alternative energy source, it actually subsidizes stronghold to burn the stuff to make bitcoin. How can this be . Oh, because of this in the toxic legacy of nearly a century of coal mining. Coal fed, the furnace is a pennsylvania is once mighty steel industry. And this waste, sprawling across the state in vast sly keeps, is the low quality material left over from the mining acid and poisonous heavy metals. Leach out at them. Bill spence is strong, whole Digital Mining chairman. I feel as if america had in the world had a party here and then we woke up the next morning with the residual garbage leftover and theyre having to clean up after the party like the state of pennsylvania. He wont say hes gone, he says hes using the States Alternative Energy incentives and the profits from big coin mining to make that happen. But coal is the dirtiest source of power there is. And coal waste is especially inefficient. So i asked bell the obvious question. Do you think that the c o 2 emissions are a justifiable byproduct of clearing this landscape . I absolutely do. And what im asking you is just stop a minute and look at this. I understand where people say its not perfect, but how many things in life are perfect. I. I mean, rory, i mean dont let perfect be the enemy a very good. So do you consider yourself an environmentalist . I absolutely consider myself an environmentalist or bill and his colleagues firmly convinced that theyre doing what is best for this area. I have a feeling people campaigning against climate change. Im going to disagree who im on my way to meet one has another coal waste power station. Right, makes my spect chimney. There are plenty of bitcoin miners who say their operations a green, but most tend to seek out the cheapest energy, whatever it source. This is russells ebay, who works for the clean air council. The interesting thing about big coin is you could do it in the cleanest way possible, or you can do it in the dirty way possible. And as long as there are government subsidies to do it, in the dirtiest way possible, people will keep burning co waste generate the coin was supposed to be moving towards the next 0 future, reducing Carbon Emissions to nothing by 2050. How does that fit with bitco in its Huge Energy Consumption . It does not the introduction of crypto currency and its Energy Consumption is such a massive step backward for environmental efforts efforts to confront climate change. Russell says several states in the us or considering banning bitcoin mining, but not pennsylvania globally, as a growing list of countries that have already outlawed it. China being the most significant one of the other things ive heard about big coin. Its a haven for criminals. Crypto links crime says to record levels in 2021, up 79 percent from the year before. I want to know whats behind this. Galvis. Greek is a former f b i. Agent who now works for a company investigating crypto crime. Criminals are using crypto. The very same reason why the vast majority of crypto users use it for that speed, liquidity, and cross border nature. What are the kind of crimes that we see around crypto . Theyre doing everything in this virtual asset world that they were doing in the regular world, particularly scans and frauds, make up the largest category of elicit use of crypto. But you dont think this actually is a problem with crypto itself. You know, theres nothing inherently evil or bad about crypto itself is just simply another method for value transfer. Criminal stole 14000000000. 00, encrypt currencies last year. Or we see any kind of state involvement in this we have seen, elicit use of hacking by north koreans. For example. In fact, theyre responsible for hacking over a 1000000000. 00 in Exchange Hacks in the past. But galvis also says the transparent nature of crypto is block chain ledger actually gives investigators a treasure trove of data to work with. So for example, if there was an elicit transaction where a little lady was scammed out of her money and they, and she said no, i paid them in bitcoin. Well they, they can look at that transaction and see where that womans bitcoin went to. And from there they can then engage Legal Process to either freeze that account or seek recovery from that victim. And thats why thats so important. Ah, my next stop is london, one of the worlds financial hubs. I want to see what government and Central Banks think of this brave new world. Easier said than done. We are so Central Banks, both in the United States and here in england to talk to us. Both of them like know why. While many Central Banks are undecided what to do about technology designed to break their control of money, ive come to meet harriet baldwin, a british conservative m p, a former investment banker, and a member of the Treasury Select Committee which examines governments economic policy. Do you think the central bank should be scared of correct, that kind of states . I think theyre all looking at it. I think its gonna be important to coordinate the approach amongst the developed world Central Banks. I think, you know, there is also the risk that these currencies could end up being the, you know, the tulip bulbs of the 21st century 15. If i was, you mean it could be a bubble. People could be buying something for way above the value that someone else will pay in the future to take it off that hands and they could lose a lot of money in the process. And that was something that they discover. Its actually just lines of code and doesnt have Intrinsic Value because no one else will accept payments. Does crypt, Currency Development poses threats to Financial Stability . It could be potentially, if it becomes a much more significant size in the well Financial Markets at the moment. All the evidence weve had on the Treasury Select Committee is that its still a very small proportion of the worlds asset base. And so therefore weve been told that it doesnt pose a threat to Financial Stability at this level box. What happens when a nation state does jump with both feet into this weird new world . How are they terminated before i come to a country that boldly gone when no other his dad and turn to self into a unique fiscal petri dish ha, is assigned to pick on bass. Now this, this is where the experiment started. Ro, salvador free is back. A clique of crypto converts began transforming the surf town of els on tape. They persuaded people to join the local circular economy based on bitcoin. But all of el salvador is bitcoin beach. Now, last summer, the countrys president and i had to kaylee, rush through a law that elevated bitcoin to legal tender alongside the u. S. Dollar. No other government has taken such a gamble with National Finances and im interested to hear what the founders of bitcoin beach think of it all. Roman martinez, his one of them was beautiful. That dream that started super small now is more bigger than our salvador, and mainly people around the world dreaming with our country. And i, jamie patricio annis, missionary 7 to portion of southern into for world banquets, and that means theyve got my bank account right now. Bank account, any kind of Financial Service a now since speaking a ride in our community, we start to seen people say, be morning people transacting digital people, receiving and making digital payments. People buying an asset for the 1st time people sending money from all saba to the us from the us each other because we can use the monitoring. T
