Bitcoin Mining Reward About To Halve

First time accepted submitter ASDFnz writes "The reward for successfully completing a block (also called mining) is about to halve from 50 bitcoins to 25. From the article: 'Bitcoin is built so that this reward is halved every 210,000 blocks solved. The idea is as bitcoin grows the transaction fees become the main part of the reward and the introduction of new bitcoins slows down to a trickle. This also means that there will only ever be 21,000,000 bitcoins in circulation.' You can watch the countdown here."

      The incentive to work in capitalism is just as shallow, just better veiled, but it starts to fall apart as well now. And please apologize when I ignore the rest of the diatribe. I have no idea where you pull those examples out of, but I better not touch that place.

      In communism, the promise was "work hard, and soon in the future we'll all be living in the socialist worker paradise". Well, people started out believing in it. No, seriously. I'm serious. Look at how Russia developed in the 1920s, they turned from a backwards agrarian society that was close to a feudal system into an industry nation within a few years. At a horrible price, no doubt about that, but people believed in it and pulled through. Well, guess what, it didn't work out. And after WW2, it became plainly obvious to everyone that this "work hard and soon we'll all be living better" is an empty promise. Especially when you see how on one hand the party idiots are being promoted and have access to things you can only dream of, and that no kind of work or butt kissing will ever give you the same. You may get ahead a bit compared to your peers if you are a "more loyal comrade", but it's just the crumbs from the cake the big players eat, and that's a circle you cannot climb into, no matter how much you try, it's a closed circle of "friends" that matched and mingled in party organizations and party training camps. Your only chance to get access to at least those crumbs is that you work extra hard "for the greater good", volunteer for "extra duty" and similar crap.

      The joke is now that capitalism works actually the same way. Well, not quite the same way, it's different empty promises and different approach, but the end result is exactly the same. The promise of capitalism is "being rich is the goal, because money can buy whatever you need, work hard and one day you have the chance to be rich too". Well, some people buy into that. Most, actually. No system could exist without enough people supporting or at the very least not sensibly opposing it. But it becomes more and more obvious that the promise is shallow, too. No amount of work will ever elevate you to the executive levels of the big corporations where the big bucks are being handed out. That's a closed circle of people who know each other from various fraternities or buddies from the same schools. Schools that you couldn't go to because your parents are not rich enough to send you there. Because they didn't have a degree from said schools to get into a position that... you get the idea, right?

      Money stays amongst itself, there's no butting in for you, peasant. But if you work extra hard, you might get promoted in the office treadmill, you'll get some bullshit title and you'll feel important because now you make the big bucks, i.e. like 200 bucks more per month. But "rich", in the capitalist sense, you'll never be. Neither you, nor your kids.

      So, essentially, whether you call it communism and make party loyalty the decider between powerful and peasant, or whether you call it capitalism and use money for the same, it's not that much of a difference. If you're not in the correct circles, if you're not with the right people, you won't get anywhere in either system. The reason capitalism works better is simply that it's harder to see through, that the lie of "everyone can get rich if you work hard enough" is compelling, especially if you get to hear about someone actually "making it". In communism, those people were "worker of the month", btw, and had about as much influence on your well being. Well, maybe it upped your monthly quota because obviously it's possible. In capitalist terms, I guess it would be something akin to "why hand out wellfare, you see there is that one guy that made it, why can't they?"

Basically, it's to prevent double-spending; if someone attempts to transfer the same bitcoin to two different people, the person who gets it is the person who had more computational effort go into recording them as having it. If the amount of computational effort in recording transaction histories were low enough, someone could double-spend by recording an alternative history on a powerful computer and having it supersede the transaction history everyone thought they were using.

    In order to encourage people to put effort into recording the history, there's a reward for doing so. This lead (perhaps predictably) to "mining", where people race to record the transaction history first in order to get the reward.

    So there is a purpose to mining, but it's only to keep the Bitcoin system itself running. If people stopped mining (perhaps because the reward got low enough), Bitcoin would collapse. (It's envisaged that once the mining reward gets low enough, people transferring bitcoins will pay a transfer fee to the miners to encourage them to keep mining, and they'd get their income that way instead.)

Purchasing physical gold from a reputable dealer (and taking delivery) is entirely unlike accepting a bar of unknown yellow metal from a stranger who just walked into your business and left with an expensive product just minutes later, never to be seen again.

      But I understand what you (and your friends) want to say. Unfortunately, preparing for TEOTWAWKI is counter to preparing for normal life. Your purchases are basically reversed.

There must be a balance, an exact instant in time when you understand that the life as you know it is not in the cards - and then you flip the bit and start working for the cellar.

      I personally don't believe gold will be valuable after the SHTF. You cannot eat gold - and food will be the top priority, competing for the first place with means of protection (weapons and ammo.) Gold cannot be sold after SHTF because there will be no market. You can always exchange a .223 round for a few cigarettes, and that barter does not require a market because both goods are directly usable. Gold is not usable, unless you need sinkers for fishing. Gold has to be exchanged on a market for something else that you need.

      My personal theory is that after SHTF there will be only two universal currencies: food and ammo. Nothing else will be even close. Perhaps ammo will be even more valuable because you cannot eat if you are dead; but if you have ammo you can get food (in the forest or elsewhere.) Additionally, food can be produced - cows don't read newspapers and they will continue their lifecycle. But ammo is a high-tech product, it cannot be easily put together even if you are into reloading. Once you run out of good cartridges and primers you are done for, even if you can cast your own [low quality] bullets.

After USSR disintegrated several civil wars have broken out; some are still simmering. And if you look back into 1990-2000 you will see rich, happy Yugoslavia going up in smoke.

      The USA has a very fragile economy. First, it's an oil-based economy. No food can be grown or delivered without oil. Significant amounts of that oil come from abroad. There are needs that cannot be cut, so even a 20% cut in supplies will send the prices of gas to the sky - and the prices of food will follow. Oil is bought for dollars, and dollars are borrowed. Same happens with much of everything else that we currently receive on ships from China. This means that the country lives on credits - and the creditors may not be willing to finance this economy forever. In essence, not only I and you are not in control of the exact date of TEOTWAWKI, but even the government is not in control. The USA has too few native industries with exportable products to finance purchase of foreign energy; and domestic energy production is limited.

    I used to be big on the BTC mining thing. These days, however, it just doesn't matter anymore.

    I got into BTC fairly early, back when it was profitable to run the mining software on a single workstation to suck up unused cycles. At that time, it was actually profitable to invest in dedicated hardware to mine coins- so I (and a lot of other people) eventually did. My first dedicated rig was a HP ML350 G5, which set me back about $4000. It ran two 8 core processors and basically sat around all day mining bitcoins.

    Later on when the GPU accelerated mining took off, I bought and built four systems from off the shelf components, and the ML350 was rededicated to running ESXi with a bunch of VMs for mining and managing the four slaves. Each slave had 3x ATI GPUs, later those were swapped out for NVidia GPUs for other various software reasons.

    Then the FPGA (and later ASIC) players came into the game. It started with development boards (FPGA boards purchased direct from the chip manufacture), but later spiralled into custom FPGA boards in nice cases that you could stack or keep around on a metal shelving system easily enough. Now, the custom FPGA boxes for BTC mining basically put the GPU miners out of business- the introduction of FPGA hardware increased the BTC mining difficulty to the point that it was pointless wasting the power mining with anything other then.

    The problem was that by the time the FPGA market exploded, it was *barely* worth investing in the hardware to get in that late in the game. Previously, buying a few PCs and loading them with GPUs was a cheap way to make some extra cash. FPGAs however cost a hell of a lot more and the difficulty of mining BTCs had increased so much that you would barely break even, and you'd be bloody lucky if you actually made any money in the end.

    But FPGAs weren't good enough. People started thinking that they could build silicon to do things even faster, and thus the ASIC market started to emerge and take off. The problem here is that while an ASIC kicks the shit out of an FPGA (and anything that came before the FPGAs)- they're so expensive and the BTC difficulty has been bumped up so much by the initial ASIC wave and the FPGAs before it... That... Wait for it...

    Investing in ANY form of ASICs to make **any** kind of reasonable money... Means that you'll never actually break even.

    That's right, the ASICs they've got out there are so powerful and the BTC chain is becoming so difficult to mine, that if you invested $10K+ (which is what you'd have to spend) for a reasonable ASIC setup- you would never actually make any money. If your ASIC box is profitable, it won't be for long since the more ASIC miners join in on the party- the more difficult it becomes to mine BTCs.

    So the whole system has kind of spiralled into nothing. Mining isn't profitable anymore. Even if you invest in serious hardware. It just doesn't matter anymore, and now that the "reward" for mining BTCs is about to halve- it's even more of a waste of time then it was before. You could have made money in the beginning if you were there, but if you weren't- it's not worth investing even a dollar into hardware to mine BTCs anymore. That train has long since departed.

    BTC is basically just a currency now. Mining is vastly irrelevant and always will be, now that we've got FPGAs and ASICs flying around.
