  • Everyone seems to want in on this cryptocurrency boom, bitcoin topped fifty eight thousand dollars

  • for the first time ever in February 2021 Bitcoin spiking, as we learned just moments ago that Tesla

  • bought one point five billion dollars of the cryptocurrency Bitcoin, crossing fifty thousand

  • for the first time ever.

  • Give me a straight line, judge.

  • But it's one hundred thousand, I think in 2021.

  • The more people that own and use it and then begin to transact on it.

  • The more valuable the Bitcoin is itself.

  • Ether The world's second biggest cryptocurrency has also been hitting new record highs this year

  • and even the price of dogecoin, a cryptocurrency invented as a joke that doesn't have the same

  • serious function and institutional backing is something like Bitcoin surged more than 50 percent

  • after an Elon Musk tweet.

  • While it's easier than ever to buy a small fraction of one Bitcoin using, for example, an app

  • like Coinbase. That's not the only way to get your hands on crypto cash.

  • You can also mine for it.

  • Before the pandemic took hold in the US, we went to a block chain production studio in Brooklyn to

  • learn how to mine for Bitcoin's biggest rival ether.

  • Here's how it works and how much it costs.

  • Digital mining is kind of like real life mining, except that instead of shovels and dynamite, it's

  • accomplished with software and computers.

  • A miner is essentially just running a computer program that solves a complex math problem.

  • Solving that math problem is how crypto transactions are verified so that money correctly

  • moves from A to B.

  • The miner who solves the problem first is awarded crypto cash by the algorithm for their bookkeeping

  • efforts. In the 12 years of history, not a single entry on its block chain has been fraudulent.

  • Now they processed probably close to 10 trillion dollars of transactions and not a single false

  • entry in the, you know, that same 12 year period of time.

  • What percent of banking system activity was false?

  • It's probably close to seven or eight percent to achieve that kind of security while being

  • completely permissionless.

  • Anyone can actually transact on this.

  • I mean, that's a pretty incredible feat.

  • Can you explain to me what we're looking at right now?

  • So this is an Ethereum mining rig, and this is just like any other computer that you would build

  • on your own only instead of having an actual case that all the components live in.

  • It's in an open area like this.

  • And you need to do this because when the GPs are running, they get really hot and it's important to

  • have like a lot of air circulation.

  • Lee learned how to mine watching YouTube videos.

  • This is back when he was still mining in his spare time.

  • And so the main components here, this is your power supply.

  • This is your motherboard.

  • This is what wires up all the logic on the computer.

  • You need to have an operating system running on your motherboard.

  • And so this is an SSD, isolated, hard drive.

  • And I have a specific operating system called FOS installed on this.

  • This is an Nvidia Gforce GTX 1080 GPU.

  • And this is a graphics card that people use mostly for gaming.

  • But these are also really good for mining crypto currencies.

  • Once this is sewed into place, we need to plug it into the power supply.

  • And then we need to plug in the data so that graphics card can read from the computer

  • and then plug this guy in.

  • So what's this last plug here?

  • So this is a SATA cable.

  • This is so that I can get data out of the motherboard.

  • So once it's all wired up like that, this is ready to go.

  • We can just turn it on and we'll start mining.

  • You just turn the computer into a rig.

  • A mining rig. Yes.

  • All in this rig cost roughly 1400 dollars because of the parts that you see here.

  • The only other thing left to do is create a wallet, a wallet is a digital address for crypto

  • cash, and then how long does it take for it to actually start minings?

  • This should just automatically start connect to the network and knows your address.

  • You'll see it start going in a couple of minutes.

  • When the rig is mining, what it's actually doing is running what's called a hashing algorithm.

  • So it's computing millions of math equations to work out all those digital transactions.

  • But this mining rig isn't doing all these math problems in a vacuum.

  • It's actually competing against miners all over the planet to be the first person to verify a

  • block of transactions.

  • Someone wins this race roughly once every 13 seconds, and whoever wins is awarded to ether.

  • They also get a transaction fee, which averages out to about 2.3 ether.

  • But there's a mining pool fee that has to be paid, which is about one percent of the block

  • price plus the transaction fee.

  • When you combine all three at today's prices, that comes out to about sixty four hundred

  • dollars. And is everyone using the same hashing algorithm?

  • Everyone uses the same hashing algorithm.

  • It's completely democratic.

  • It just depends on the hardware that you have and the cost of your electricity.

  • So the only advantage you would have is if your GPU runs faster than someone else's or your

  • electricity is cheaper.

  • Yeah there's no way to shorten to shortcut it.

  • This rig with only one graphics card can run roughly twenty seven million math equations every

  • second. That sounds like a lot, right?

  • But on the theorems network right now, there's 400 trillion math operations happening every

  • second. So Lee's rig in Brooklyn accounts for around one 15 millionth of the entire Ethereum

  • network. That's why people join something called a mining pool.

  • A pool lets a single miner combine their hashing power with thousands of other miners all over the

  • world. They could be in Afghanistan.

  • They could be in Dubai.

  • They could be in Europe or South America.

  • You're all sharing your resources together and it doesn't matter where you're physically located.

  • So you are working together with these people to compete to solve a block faster than anybody else.

  • It's one giant competition between everyone that's on the network.

  • So it's a race between you and your computers and the computers in your mining pool versus the

  • computers and other mining pools.

  • let's fast forward an hour teaming up with my mining pool.

  • Here's how much I managed to rake in as a miner.

  • OK, so is it actually worth it to spend all this money on gear and electricity in order to mine for

  • crypto coins? Let's look at the map.

  • Our one graphics card rig costs roughly fourteen hundred dollars.

  • Tack on five more graphics cards and we're forty four hundred.

  • If we run this rig at full capacity with all six GPUs, it can earn about 0.348 either per month,

  • which is roughly five hundred and fifty dollars.

  • These rigs require quite a bit of power.

  • So electricity cost is a big factor.

  • Where you live in the United States also plays a major role and how much it cost to mine.

  • Since there are stark differences in electricity prices from state to state, Alaska, Hawaii,

  • California and Connecticut have the steepest electricity costs in the country.

  • New York is also one of the priciest states where electricity bills are concerned.

  • So it doesn't necessarily make sense to mine here in New York.

  • But it's a totally different story where electricity is less expensive.

  • Just take Washington State.

  • It's got some of the cheapest power sources in the U.S.

  • So there the profits can outweigh the costs.

  • Outside the US, the prices drop even lower.

  • A study released in twenty eighteen by Elite fixtures show the countries like Egypt and Kuwait

  • are among the places where it is least expensive to mine for Bitcoin.

  • But one important thing to keep in mind is that the size of the prize that miners win

  • exponentially decreases over time, back in 2017, it was five ether, but it's been cut down a few

  • times since then. Rewards are now 2 ether.

  • But again, you get a transaction fee for each completed block and those fees, something they

  • call gas prices, keep going up.

  • So there's definitely still money in mining for Ethereum.

  • And unlike Bitcoin, there's no cap on the total number of ether coins you can find.

  • The supply is endless.
