I don't think it exists because every businessman wants a profit and if the price has gone up then they try to release the bitcoin into the global stock market, maybe right now, yes, this is true considering the relatively low price, they will try to choose to survive rather than them selling it at a price that does not match what I want, and if the price returns to normal then it is not impossible that I will also sell bitcoin
Agreed, if they have brought a large capitalization for such mining, their plan would be to sell bitcoin as soon as the price is as high as possible, the aim is to restore some of the initial capital, next is to think about the profit levels after months of trying to recover capital. Furthermore, the cost of equipment damage and repair as well as the usual costs of living, a small mining system also requires a relative fee, other miners will surely take advantage of the quick sale opportunities to secure their own interests
