another discussion would be the market reaction in which case the type of ETF wouldn't matter. the market may see the news as positive or a buy signal and start buying hence push the price up as it works with any other positive news.
Up till now, I still do not know why we still so much give so much attention to the price of bitcoin associated with ETF as the case may be, and I do not even believe any serious conclusion regarding that will be made this year, but absolutely because of the speculative nature of the market, people will always want to assume some possibilities for the market. The market has been doing well without ETF and I do not see any reason it should stop doing well without it in the long run.
I think when we have a Bitcoin ETF, that the price will go to 50.000 USD.
You must be wrong. Why not 100,000 USD or even millions ? I believe before an ETF gets approval, we are going to see prices to breach $30k levels too. I mean SEC may take some time and in between times bitcoin will prove its own capabilities.
