There are several groups trying to create cryptocurrency ETFs.What will happen to the value of bitcoin if Bitcoin ETFs are approved ?
A day is coming when this ETF will be approved and by then we would see how bitcoin is going to react to it. However, I am thinking ethereum will be the most beneficial as many ETF tokens will be louch on it. Bitcoin will actually go bullish and it might get another moon because of the new investors coming into the market.
For ETH to get an ETF of its own Bitcoin first needs one. It won't be the other way around.
However I don't see an ETF for ETH anytime in the near future due to the problem that it still might be considerered a security.
Another issue with ETH is the tokens that it supports where a large portion of them ended up being pure scams. This won't go well with the SEC.
At first a BTC ETF for a few years to test stability and volume and active interest and then maybe an ETH ETF might be in the works.
