Retail brokers typically end up making ~$0.001 per share + commission + fees + interest on cash balances + financing spread from margin lending and stock loan
Robinhood makes $0.001 per share + fees + interest on cash balances + financing spread from margin lending
I'm skeptical Robinhood will ever be able to become profitable. They're great for the consumer (except for their heavy marketing of margin lending), but I don't see them attracting the power users they need to make the business model work.
If you do use Robinhood:
1) Build a well diversified portfolio (30+ companies) 2) Don't use leverage 3) Don't trade on a daily/weekly basis
This is sensible but Robinhood doesn't have fractional shares (it would cost something if it did), so you're really raising the bar on minimum investments here. If you just bought one Vanguard ETF and did nothing else, that'd be a great plan.
IB Commission is $0.005 per share, with a minimum of $1 total. The problem with IB for regular folks is a bunch of monthly fees if you don't have enough activity each month.

I have an IB account, but even setting that up to trade properly requires owning a company. I did wake up early and trade the US options market a little while ago & that was pretty great. Might play with some algorithmic stuff I have that works on the ASX, but on the US, just need a load more data.
Except Austrian tax laws, which will make me close all that anyway...
I think the way it's being promoted is a bit dangerous though. It seems like they're promoting to the exact market that really, really shouldn't be flipping stocks (and promoting use of margin to do so). Interactive brokers is what, a few bucks a trade anyway?
Something aimed at a similar market that I like a lot more is 'acorns'. It just rounds up any transaction you make to some number, and invests the difference in one of a few ETFs. I think it promotes a much healthier view of investing for the average young joe/jill.
