First of all these ETF's are cash settled, so to what extent Blackrock will accumulate "all the Bitcoin", I'm not worried. Even if they somehow managed to pry Bitcoin from our cold, dead hands, 6.25 more are created every 10 minutes, and not by Blackrock. That 6.25 is what pays for mining, Blackrock can't take it from them before they sell it to keep mining going, and they won't sell it if the price doesn't pay their bills. And even if that were true, and miners couldn't afford to mine any more, and switched off their machines, then what? The difficulty to mine would drop until it was affordable again, and they'd come back. And you want to tell me Blackrock wants to buy all the Bitcoin in the world, spend all that, and then make sure it's worth nothing? Please.

This article wants you to sell, straight into their hands. Ignore.
