Thanks to Nasdaq, we will certainly have higher prices, but unfortunately the consequence of manipulation (as everyone know, they like it there) may be very bad. Because of whales from Wall Street, normal crypto supporters can lost the last faith in decentralization and Bitcoin success. If that happen in the near future we can see the bottom for Bitcoin at the level of $500 or less.
Firstly, it's not even sure that they'll be launching their futures market because they need regulatory approval for that, which they don't have yet. Secondly, it's impossible to know if it will stimulate the market positively.
The only **potentially** positive aspect is that more futures markets within the US could make an ETF approval more likely than is the case right now, but that's pure speculation from my side.
As for the manipulation of the market, I'm not concerned about it at all. I would even like to think that it makes manipulation more expensive/difficult because it's yet another market to play, and you can't control every market as if it's nothing.
