This money is solely a market money, it won't go for the development of something new or innovative. If we talk about a year or two prior, such institutional money was flowing into ICOs or crypto crowdfunding. I agree that ICOs turn out to be epic fail as the time progressed but still money was flowing for the development of something new, something innovative in crypto domain. And even in the failure, we got some serious break-through in crypto industry. But now this money don't actually gonna give fundamental benefit to crypto industry rather it would disturb (will make more volatile) the crypto market due to excessive leverage play by the big investors.
Well, that's the same as the 2/3 of us actually using cryptocurrencies, they're not here for the tech or the development or whatever. They're also here only for speculating and take their profits.
What's the difference in terms of motivation? When it's institutional investors it's a problem but when it's random individual it's not anymore a problem.
Volatility is also what attracts people to gamble their money in cryptocurrencies, let's be honest. They all expect a pump and dump movement to make cash. If Bitcoin's price was so stable people wouldn't come.
