Robinhood's original referral promotion (and the one I signed up for) was $10. Presumably people were just collecting the $10 and not using it to buy stock so they pretty quickly changed it to "1 stock." If it were still $10 the person would have made $230 rather than losing money.
Also, what's the TOS on this referral promotion? IIRC, for many services these referral codes are for private distribution and forbid this sort of thing.
