yeah that was kind of a red flag for me as well. I would sure like to buy or short some stocks for free, but I always heared it is bad to use leaverage and ofc I wouldn't use it at first, but just when I blow up my account to 100$ and get overconfident I will use the 10x leverage on a superrisky trade and bam, now I owe them 1 Grant.

Thats just a hunch though, I might still look into it
