On the one hand I am obviously happy when the ETF gets approved. There is an ocean of dollars out there that can't use Coinbase/Kraken/Binance and the like. On the other hand I notice I am a bit sad by the thought of it, Bitcoin will never be the same anymore afterwards. It leads to more centralisation and retail buying ETF shares will never learn to self custody and transact in bitcoin (and therefore fully understand and experience Bitcoin). Creating paper bitcoins is a very tempting threat. Wallstreet will love their new and volatile toy for daytarding and there are heaps of trading fees to be earned by the exchanges, encouraging it to change hands like a hot potato. I can even imagine once Blackrock and the likes get a decent market share they start to have an opinion on blocksize, which transactions should and shouldn't be in a block, etc.

Let's see how it evolves, can't do much about it except for not buying those ETF's and hodl your own coins.
