I must remark that, for the bankster cartel, $100B is lunch money. They may well own BTC's, but why should that bother the rest of us? They're not mining, and so can't pull a Sybil.
I have no BTC, and so have no dog in the fight. Sadly. I am not averse to profit, honestly, but I also have lost amazing pics and data because of equipment failure, so just can't bring myself to store value in the cloud.
Plus, I can't remember my own birthday anymore. How am I supposed to remember my wallet, password, and to put my teeth in, all on the same day?
The big banks make a ton of money rigging markets. The other day when cryptos tanked you and i were locked out of the exchanges but the cryptos tanked cause the big guys were selling not the little guys. Same shit different game.
