Many had speculated that once Wall Street got involved, with robust servers capable (and used to) handling enormous amounts of traffic, they would blow away traditional Bitcoin exchanges. Apparently, even mainstream Wall Street firms are going to have difficult dealing with Bitcoin’s demand.
Since they aren't transacting in actual Bitcoin, or if it's held, the trading is all done off chain, they aren't really in competition with "traditional" Bitcoin exchanges (and slightly OT, but is "traditional" really the right word when exchanges are, much like Bitcoin itself, still less than a decade old?). The same goes for ETFs if they eventually get clearance to go ahead. None of this stuff will ever touch the blockchain itself. But with exchanges, once you withdraw the funds, they're safely on the blockchain and they belong to you, guarded by your private keys. I'm pretty sure that's not what the banksters are doing.
Wall Street technically isn't "involved" when talking about futures and ETFs, they're merely watching from the sidelines and making a few bets (which may still have some impact on the fiat price, but it's still not the same thing).
