There are several groups trying to create cryptocurrency ETFs.What will happen to the value of bitcoin if Bitcoin ETFs are approved ?
There will be temporary effect in the bitcoin prices but it will make the volatility range of the cryptos to increases because there will be lot of investors who will make the coins to bump and dump and in long term the price growth rate maybe decreased because the prices will swing at some particular range because of the big investors.
We never know until things already happened, but in terms of price surely it will spike up after the approval, most expectators will begin to buy in when things shown positive, effects as investors will be more widely even new big whales will start playing buy and hold, those people who will accumulate and allow the price to pumped up are just waiting for the right timing after this decision.
