I don't think Bakkt moved or delayed their opening to actually be at the same time as those two because they needed the upper hand and be early at ETF in order to get as many customers as they can however if what is said is true and nasdaq and nyse is actually starting etf for bitcoin I think it will be amazing for all of us. Think about it when the investors wants to buy bitcoin ETF and they lose money do you think they will comeback to that investment bank? I don't think so, they are not going to be like "oh the bitcoin didn't work so lets do something else" no they will be more like "your investment didn't work I am taking my money somewhere else". Hence banks will have a lot of incentive to keep bitcoin price above certain price in order to keep customers happy.
