Don't feel like quoting everything because I'm a lazy asshole but basically
1. Re: The idiot at JP Morgan: He calls it a fraud and says he'd fire anyone in the firm buying it, yet they're firmly invested in ZEC and he also admits they have people they hired dedicated to this line of work. They have BTC and his use of the word fraud is kind of lol. As if he's saying there's some mysterious group of people behind bitcoin that are profiting off of every public transaction.
2. Re: monsterj trying to act like there isn't heavy exposure to most financial firms to bitcoin. Whether they're invested directly with funds in BTC or not, they still are invested in these projects thoroughly and they definitely have their hands in ICO's and other crypto based packages and services online. For reference see 1 above.
3. Re: "hurr durr it's hard for large investors to break into this market." You're forgetting over the counter trades which consist of a very large part of the people who buy in for very large sums of money. Throw out somewhere worthwhile that you're looking to sell or buy over a mil in BTC at once and you'll get hit up rather quickly. I've met people that arrange these for 5% commission. There's also the ICO's which made it very easy to get exposure for the wealthier investors.
4. Re: hedge funds aren't allowed to buy in because it's illegal. The US isn't the only country in the world, get over it.
