Backup generators, lol. You don't even see that your post is self-contradictory (this part, and especially the next part). Miners mine for profit (I guess this won't be a matter of dispute). That means once they hit break-even they don't need to sell all their newly minted coins but only a fraction to compensate for operating costs...
You don't seem to think things through before you reply.
Not all mining farms are built months or years ago, newer farms may not have reached break-even point. You have said so yourself, "
once they hit break-even". How about before the "once"? Before the farm break-even, owners could sell all their mined coins. There are many farms out there built at different times. Yet,
you seem to believe each and every one of these farms "can't be selling everything (bitcoin)".
If you have problems with proper understanding, I can explain it to you. "They can't be selling everything" means that some of them (or just one) don't sell all the coins they mine. In other words, that some newly mined coins won't be sold. If I wanted to say what you are trying to ascribe to me, I would have said "None of them can be selling everything". But nevertheless, show me
here a mining pool which was not "built months or years ago" that would have a significant share of hashing power...
Or just any
new mining pool that would be of relevance, for that matter
