That is a pretty small number percentage wise, but the actual figures could be way bigger.
Honestly, I am surprised that the institutional investors are investing that much money into cryptocurrencies without the ETF proposals getting approved.
Imagine the price of a Bitcoin if the ETF proposals were approved in this scenario.
There 'could' be a lot of money coming from institutions if a Bitcoin ETF proposal would be approved. So we have to wait and see, the thing though with this scenario is that it's not on our control.
Maybe those 7% have been in the crypto sphere prior to the peak and didn't go out when the price burst in 2017. And then there's no money coming in from them because of the worsening market conditions. But then again, this ball park number will also fluctuates based on the market, if we see improvements or at least a bull run in the future, I'm expecting it to increased by many folds.
