Huge amounts of money have yet to come in. I'm talking about pension funds, teacher retirement funds and large index funds. They're not in the realm of cryptography right now, but they're just around the corner. There are two reasons. First, there is a lack of hosting services to help them provide/buy/store passwords. Second, it's too unstable for them. That has turned most of the big money going into crypto into technology-focused venture funds and some family offices.
I think it won't enter any time soon. We are talking about "big" institutional money and if its really that big it should be over 100's of million dollars for each, a total of billions of dollars together.
We are having trouble whenever someone sells 15k bitcoin and our market cripples and stays low for a long time when that happens, 15k bitcoin worths about 100 million dollars right now, if one 100 million dollar made our market this way can you think how much billions of dollars would affect the market ? For better or worse it would change the market drastically. Noone in their right mind would invest hundreds of million dollars into something this fragile.
