Retail will not enjoy a shit market where everything trades sideways for months or sees the major indexes bank countless down days. They won’t enjoy allocating capital on any of these platforms (and so they will disappear, until the next boom).
It’s almost a matter of loyalty with retail honestly.
What I do see changing is pricing. Robinhood proved that it is a viable business model for brokers to monetize interest on non-invested balances instead of charging per trade. The pricing will definitely go down in the future, and there may be more experimentation with other pricing models.
People buying options, leveraged products and CFDs not understanding what they are buying and getting burnt.
More "influencers" with no prior track record pushing stocks.
More retail investors loosing money
People will be smug their > 100% gains but not sell down and loose it all
I see a lot of naive people loosing a lot.
Why do I think this? - Because I have done all of the above.
I bet in 10 years time such firms like Robinhood and IG will have "Gambling aware" banners
