The debate is still on-going if large investments from institutional firms, would be good or bad for Bitcoin in the long run. Some are saying it will bring more volatility and others are just happy that the price will probably go to the Moon.
Institutional investors will be the BIG losers. They are only making early bitcoin investors rich.
Here you go again with you big theory here. As far as I know when CBoE and CME enters the markets, the price suddenly spike resulting to a all-time-high. But it wasn't that sustainable though, that's why they losses a big chunk of their investment specially coming 2018 with a long bear market. As far as making early investors rich, it's their advantage, they see Bitcoin's potential and it was realized in 2017, but we don't have to blame them though.
