Not really. What we're seeing right now is short term volatility, and nothing other than that.
In the long run, I think that bitcoin would still be a much better store of value than something like fiat, which has proven that it would drop in value imminently, and consistently. I'd much rather store my wealth in something independent like BTC than a government issued and controlled fiat currency.
These institutions that you talk of are actually becoming interested in crypto on a massive scale. I don't think that they are the ones that are pushing prices down at all. It's just a normal phase in the bitcoin's price cycles, which iterate every few years. Futures could be the source of some manipulation, but it would be hard to see how they can be stopped.
