Who has inside information on what miners are doing now? Are they selling everything?
They can't be selling everything, you don't need insider information to understand this.
I can't agree with that. Mining farms are built with fiat. That includes building costs, hardware purchases, and backup generators. The infrastructure could be financed with loans. Loans have to be repaid, or owners may want to sell mined bitcoin to offset initial investments until the fiat breakeven point.
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...
I guess you have to decide for yourself whether miners earn profits or not. If they do, they don't need to sell
all their mined coins
