It's one of the crappiest scaling solutions for Bitcoin, ETF shills make drivechain shills seem super reasonable, lol its all bag pumpers wanting their Bitcoin to be worth millions so they can live a fiat consumptive lifestyle, I don't pay attention to those opinions

Like you say it's coming eventually in the US and is already live in other countries, and honestly, I think some ETFs will fail, either through mismanagement or hacks

While there is still an incentive to go on-chain, as a on chain user I pay fees when I transact as an ETF I pay management fees every year, so ETF holders will gradually end up with less BTC versus on-chain BTC

As for now, we kinda need it in a way if it brings more interest hopefully a portion of those people migrate to real bitcoin and put pressure on scaling solutions like LN so we can see what this baby can do
