There are many spot etfs in many countries already this is nothing new. I think somewhere in Europe there was a bitcoin etf from maybe 5 years back.
USA and the sec is the only country pretty much that refuses to launch one and we don’t know why. Look at how many stocks go bankrupt like Bed bath and beyond and they head to $0 while they think that bitcoin network might stall and the etf will go to $0, highly unlikely.
In many countries? How many and what are these countries? I am quite certain that there are not many countries offering spot ETFs for bitcoin or other cryptocoins. Also, if it is a spot ETF in a developing country with a small market, we can also be quite certain that it will not have effect on the whole market.
On Bed Bath and Beyond, you cannot compare hehehe. I do not know the story but the stock goes to 0 because the company behind the stock went bankrupt and if a company goes bankrupt, they are ordered to delist their stock from the stock market.
