Coinbase is the perfect example of that with how they pulled back their institutional focused index fund due to the lack of interest, lol.
That. They took care of the custody aspect, were entirely legal, and granted exposure to both Bitcoin and the altcoin market. It's a solid combination on paper, but not enough to draw attention from institutions.
2019: Institutions are about to enter the market.
2020: JPMorgan plans to create trading desk.
2021: Bullish news for Bitcoin, Vaneck ETF might be approved soon.
I can remember that this nonsense started back in 2015 and maybe even before that. By the time institutions finally announce that they are in, you can be sure they have been in for years already.
