Sales != profit.
And again you're whole argument seems to be that they're so profitable they can do whatever they want. Even if that the case in one instance, clearly that's not sustainable on a long term scale
Not one instance, most instance.
Tell me exactly how it is not substainable? I should add that most of these companies are now setting up cloud mining services and selling mining contracts at what are most certainly extremely high profit margins.
What is not substainable is this persistent bear market in the face of continuing innovation and development in Bitcoin's infrastructure.
When the price starts shooting up again, these companies will be even less enticed to sell any Bitcoin.
It seems to me you have little to no argument and keep moving the goal posts. I, on the other hand, have brought forward numerous arguments and factual reports to indicate that miners are not all dumping to fiat the BTC they mine.
In one word competition. If it's so profitable what's stopping 100 new asian manufacturer coming online tomorrow at the fraction of the cost and driving hashrate through the roof squeezing those profits? What about Intel entering the market? It's always a risk/reward game you won't see crazy profits for too long, but when you do and first to the game you reinvest to try as grab as big of the pie early on, not hodle because you get way too much money from other business.
So they're not dumping now, and even less likely to dump when market goes up. Perpetual hodlers?? Great business plan with no exit strategy, but even if that's the case and 1% ASIC manufacturers horde up all new coins there's the risk of the other 99% revolting and hard forking you out of the game.
