Specialized devices for mining BitCoin (ASIC). What is the point of selling them?

Question

Iron

Hello Habrocommunity!

I am driven by curiosity and desire to know the world around me. I found several places that sell specialized boards / external devices for mining BitCoins. Among the devices, I found those that, according to my calculations, should pay for themselves in a month. Even if my calculations were wrong somewhere, then let's say 2-3 months ...
So, the very question that has been tormenting me for a long time: what is the reason to sell such a device? From the outside, it looks like getting rid of the goose that lays the golden eggs... Why shouldn't the manufacturer launch all the devices at home and get rich in a couple of months? Or is there some advantage in the BitCoin system from the fact that they will be mined not at one point, but all over the world? Or does it make some other sense...
If anyone knows, please share information.

Answer 1

Why do states bother with production, trade, and do not print as much money as they need (bad example, yes)?
If the sellers of the miners start mining themselves, all their bitcoins will turn into shards .

Answer 3

I was seriously considering investing a large amount of money to mine. But I carefully analyzed and realized that I was observing a typical financial pyramid. Moreover, with the development of the production of ASIC-chips, its collapse will be approaching, because. the depreciation rate of mine farms will increase, and it can already be said to be high even now.
Using the example of some comrades, now let's say a 5TH device will hardly pay off in the coming year. Considering that 500-600Tx machines are being prepared for production, it can be unequivocally stated that the rate of complication of calculations will become even higher. Therefore, miners with video cards can already be considered in flight.
As a result. Miners buy the illusory hope of profit. And ASIC chip manufacturers are getting quite real money here and now.

Answer 4

This is not a pyramid, this is a high-risk investment, those who were the first to take ASICs for mining have already paid for them and made a profit, the rest can already fly by. Or they may not fly if the course jumps up.

Answer 5

I also join the above and add only that we must not forget that the complexity of mining is growing all the time + the risks are growing, which is why it is easier now to sell several thousand devices and get real money. No one knows what will happen to this cryptocurrency “tomorrow”.

Answer 6

I re-read all the comments, unfortunately they do not correctly indicate the problem. I will answer as a former owner of the miner. Judging by the date of your post, then on this date there were no longer miners who would have paid off, if you nevertheless calculated that they paid off, then you 1) either made a mistake in the calculations or 2) did not take into account the increase in complexity 3) or simply use a calculator that doesn't take #2 into account. At the moment, there are no miners that would pay back their price.
-- added --
Although I see above they wrote about the complexity.

Answer 7

Or is there some advantage in the BitCoin system from the fact that they will be mined not at one point, but all over the world?

Yes, that is exactly what bitcoin is all about. It is necessary that a situation does not arise that more than half of them are concentrated in one hand, otherwise these hands will become a monopoly, the one they wanted to get away from by inventing a distributed currency.

Answer 8

Significant investments are needed to develop and manufacture such devices. In addition, the risk is very high, because no one guarantees that the devices will pay off in 3 months. There is a big chance that bitcoin will depreciate to zero in these 3 months. And so they have a well-planned business, and they are guaranteed to earn, because they take an advance payment. And, I think, they also do not forget about independent mining, i.e. for themselves, they make as many devices as they need.
