Hearing you can use it for laundering illegal cash then snowball it into millions. How? How can you convert it back to legal tender? Discuss

    ...is nobody going to explain Bitcoin to me?

    It's a fictional currency used to arbitrarily assign a value to a commodity (in this case GPU output while decrypting Bitcoin ledgers themselves). Kind of like the dollar in that artificial scarcity, ginned up demand, and the whims of traders determine the value, and it's backed up by largely nothing.

    It works like this: Bitcoin is a decentralized currency, meaning no banks, no identification, completely encrypted and anonymous. This is its value. The argument against Bitcoin is that there is no legitimate reason for this to be valuable other than in conducting illegal business. I suppose, though, there are also people who want to say, "Fuck the big banks" and be obstinate, and I can certainly relate (although I'm way too lazy). The currency is only valuable, then, if the encryption is very strong. The more people who use the currency, the stronger this encryption gets.

    How?

    Bitcoin "miners" strengthen the currency by testing the encryption 24/7. Bitcoin transactions are kept on an encrypted ledger known as the "blockchain," and miners build GPU farms that poke and prod at the encryption until they brute-force and and decrypt. GPUs (graphics card processors) are used instead of CPUs (general computer processors) because they're specifically good at executing these kinds of calculations very very quickly. So some nerd in mom's basement would buy ten boards that you can plug four graphics cards into each, buy 40 of the most efficient graphics cards on the market (the largest expense in this kind of operation, believe it or not, is electricity, so TDP, thermal design power, is king), and start them mining Bitcoin around the clock.

    Every time a miner successfully decrypts a blockchain, he/she is rewarded with a transaction fee and a number of new bitcoins that halves itself every time a certain threshold is met, never to exceed 21 million Bitcoin (to maintain the artificial scarcity). The encryption is also strengthened, so it takes more GPU clock cycles to decrypt the next one.

    I never cared about cryptocurrency until I had the desire to upgrade my graphics card. I'm a hobby videographer (mostly family videos and whatnot), and when I upgraded to 4K recording gear, it became clear that I also needed to upgrade my graphics card. Like blockchain decrypting, video encoding/decoding is where a GPU shines, so memory and CPU power takes a huge backseat to, say, number of CUDA cores and clock speed of the GPU when it comes to video rendering. My usual math when buying computer components is to start at the most expensive available (the latest and greatest) and scroll down the price list until you see the first huge jump--it's always relatively close to the top--then buy the next thing below that gap. It's usually either last year's whizbang card/chip/thingy or the current mid-grade model that's barely worse than the current whizbang but one-fourth the cost.

    Anyway, this was in 2016 or so, when Ethereum was the hot cyrptocurrency, and I scoured the web for the usual high-value graphics card, and I was surprised and confused to find that it didn't exist. At this time, the GTX1080 was the top of the line $800 card, and the GTX1060 or GTX1050 would have been my sweet spot. Due to higher TDP (more calculations per kW consumed), the cards that would usually be in the ~$250 range were selling for MORE than the top-of-the-line cards! And they were ALL on backorder. Forever. Total global sellout. Every single mid-range graphics card in the world had been gobbled up by Ethereum miners and put to work, such that the demand for these cards raised the price far higher than the MUCH more powerful top-of-the-line card de jour.

    I ended up experiencing severe clenching of my cheap butthole as I ponied up the $800 for a graphics card that cost as much as the whole workstation I put it in. It's all that was available! On the bright side, it was the first time in my life I was ever working with a current top-of-the-line component, and it truly blew me away what that card could do for its time. Still a great card today.

    Lol I did my first PC build in 2017. Awful time to do it. Scored a gtx 970 off a shady dude off Craigslist for 120. Which was an amazing deal at the time. Still a good 1080p card.

    Alright, I finally bought some BTC and ETH for diversifying my portfolio and for a fun learning experience. Wish I'd done it back when my friend was trying to tell me to at $100 BTC but whatever. We can't all be Husky boosters.

    I actually read through numbers' post and I still don't understand what it is. Is it valuable because it's valuable? Turtles all the way down?

    Can someone take another crack at this? The more people use it the stronger its value. Ok. Use it for what?

    PornHub only takes Bitcoin now because credit card companies cut them off due to child porn on their platform. Also major investment firms are buying in. Plus it is massively out performing gold for wealth retention.

    (Not a Bitcoin owner, but I get why it is going well)

    So is the basic idea that we? create our? own currency and say "fuck it" to legal tender and try and create a market for its use. Bartering economy with a made-up currency? Like, "it has value because we all collectively say it has value" kind of thing?

    Just psychologically, can you explain for me why it's outperforming gold? What controls its scarcity?

    Or is this like the white devil's beads and liquor and we are all going to get @Swaye 'd one day?

    It’s baseball cards, it’s art, but is much more liquid. Just another place to stash wealth. I’m not invested in Bitcoin, but if I lived a corrupt third world country, I certainly would if I had wealth.

    That's helpful. But, baseball cards and art have natural limiters. There's inherently built-in scarcity. If you could just create more Van Goughs, then none of them would be worth anything. A close cousin to @RaceBannon 's "if everything is racist, then nothing is racist." And, baseball cards and art have another function: people like possessing them just because of what they are. They like looking at them and owning them even when they're not thinking about money.

    So what's the limiter on Bitcoin? Who decides on quantity limits?

    Baseball cards and art have been counterfeited or produced in larger quantity than advertised. Baseball cards and art are not liquid assets, not often used in transactions (nor are they designed for it, like Bitcoin), plus even smaller investors can jump in on Bitcoin unlike fine art. Also, unlike gold, art, baseball cards etc., you will not potentially lose your asset if your home is raided. In certain countries, it is very important for this type of safe wealth storage.

    As for scarcity, it takes a massive amount of electricity to power the complicated computing. Bitcoins aren’t created out of thin air or on a printing press, they are “mined” by people willing to have servers and consume lots of power. As Bitcoin presses further, the computations become larger and larger, meaning more power consumed.

    Bitcoin plans on maxing out at 21,000,000 in a few decades.

    I have two concerns, both long term, not short:

    - eventually AI may be able to beat Bitcoin’s encryptions

    - After they hit 21,000,000 what is the incentive to continue powering the Bitcoin “grid?” I suppose server farm “banks” may have an interest, since there is value in being able to safely store wealth

    This is fascinating to me.

    I completely understand the inefficient markets and illiquidity of art and cards. I get that. But counterfeited cards and art just mean rip off. That's external. Assuming you're dealing with the real thing, it matters that there aren't more of them. I have a friend who owns a few Chagalls. Not the super high-end stuff that sets records at auctions, but a few nice pieces in that $15,000 to $80,000 range. She tried to talk me into buying one from her source when she jumped in. One drawing and one oil and something else I think. Anyway, the verification process she went through was pretty rigorous, and the art world would agree she has a few Marc Chagalls. They have gone up in price exponentially, and now I wish I'd bought one. My hesitation was protecting it. Would I ever again go on vacation and not think about some kid stealing a $40,000 lithograph hanging in my living room? Or my house burning down because my wife forgot to blow out a candle? So the real deal is valuable because of scarcity.

    I hate to keep doing this and apologize for being dense, but can you amplify the "mining" and computing power part of your explanation? Is that to say that someone has to create a powerful network for these things to exist?

    And, one last thing: isn't the promise of a 21,000,000, or some other number, limit pretty critical to all this? Who is "they"? Who will decide that?

    I’m not a tech guy but I believe a Bitcoin is created after certain complex computation occurs, which requires tons of power. Again, not tech guy but reading between the lines with my non tech brain, once the encryption calculation is met, a Bitcoin is mined. Every subsequent “mine” will require even more power than the previous. This mining can occur on massive server farms or even networks of smaller computers and devices. I heard that some sleeze Bitcoin apps will use your device to help mine. In Iceland they built geothermal powered server farms.

    As for the rest, I am still learning. I haven’t jumped into Bitcoin yet, by friends of mine have with amazing success.

    ^ super helpful explanations. I assume the efforts and power devoted to encryption is to make each bitcoin one unique individual item of currency, right?
