If I were you OP, I would not expect much from ETFs since they won't impact the market that much because:
I'd like to say the same thing as well that don't expect too much with it but understand what really ETF's are. It will determine a small price pump but just like what others said that you have to know the details regarding it. Just like what's with bitcoin futures before, a lot of people doesn't have an idea about and is only thinking about the spikes. I also agree with those that said it will create a short term pump and later on we'll be back on where it used to be. Well, I don't know if SEC is playing with this they keep on delaying it.
Yeah it could very well be a simple kick to excite newbies if it does get approved but nothing like what they're expecting. It won't have a lasting significant effect that's for sure, considering that many crypto supporters aren't really in favor as well of etf.
Because of most of the newbies are only thinking that if ever ETF's would be approved there will be a rise in price.
They don't care about the other things or they don't even know what does that ETF really means. That's creating a domino effect for others so they are in favor of the ETF and only thinks that its the only hope that we've got to be able to make the price goes up again.
