It might be good for speculation and the price, but ETFs will not help in what the real bitcoiners want. Adoption.
Also, ETFs are only good for those few large specialized investors called authorized participants because they hold your bitcoins, while you hold a useless ETF.
Sticky this shit,people need to understand this. I mean, ETF takes the whole "fun" part in bitcoin, I enjoy everytime I install/use a wallet, send and receive coins, check for confirmations in block explorers.
I reckon the approval will pump bitcoin, but it will also dump bitcoin after a short time when the news of the approval is released.
ETF can cause a big bull run, make no mistake. But it won't get accepted, mostly not. Do you honestly expect that a Centralized organization would approve something decentralized? Don't forget that US is afraid of bitcoin.
ETF has already been rejected twice at least, so take a hint.
