I don’t care to debate the merits of crypto, I am more interested how come the major US exchanges and players (Coinbase, BlockFi) all go down and then all come back up at the same time after bottoms were reached and the rebound. That’s incredibly suspect and warrants investigation. I’ve never not been able to access my ETrade account and trade (don’t bring up Game Stop) that didn’t affect ETrade and was debunked why they had to limit buying.

It’s not sketchy at all that price movements on exchanges are seemingly simultaneous. it’s because of automated arbitrage. Another factor (the prevalence of which is hard to measure) is that those who want to buy or sell large amounts (is whales) will chunk their orders and split them up across exchanges. These, especially the former, are signs of markets maturing.

  Effective arbitrage is nothing special, but that the platforms go down and prevent trading is. On reasonable market people should be allowed to make money with price going either direction.

    Aaah, I thought “going down” was referring to the price moving.

Was it also suspect that Walmart, Target, and Amazon sold out of PS5s at the same time? Large price movements create high trade volume on all exchanges which overload all the exchanges. AFAIK the real stock market is large and mature enough to not have crazy swings in volume.
