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.
If Nasdaq or Bakkt contracts are physically deliverable and these become sufficiently deep markets with high volume, they could have a significant effect on spot market prices. It's possible they could even lead the market. This is totally dependent on liquidity and volume. This is a stark contrast to the cash-settled markets, which basically have no effect on spot prices at all.
If regulated U.S. markets gain more influence over the global market, I think that'll improve chances for ETF approval too based on what Jay Clayton and others have said.
