Robinhood is cool. Unfortunately it's available only in USA and Australia from what I know.
Man, I only wish I could use it too.

I think when it comes to Cobinhood tokens, you have to trade on margin with their tokens instead of USD/EUR/BTC etc. to get that 50% discount. That way they will encourage adoption.
I think they will open trade in the beginning of this November. So we should find out soon.
Honestly, I'm happy without margin as long as I don't pay anything in trading fees.
I mean, I can basically buy and sell every small move lol.
I hope they will keep their promise and deliver. If so, I'm sold :D
