They're already on their way to trying to control the market, but might just get more serious which obviously I don't wish for any of this to come true.
Well they can try to but the bticoin supply isnt primarily hold by certain group its consist of separate group some are OGs of bitcoins that dont let the supply be overtaken by insitutions. Yes they could buy a lot but still the bitcoin community is stronger than them. Even though they use a lot of money on manipulating it its not gonna go on their favor.
