Stock derivatives

I am trading stock derivatives on a regular basis here for several reasons: a. I don’t have to deposit a lot of money. For the comparison stocks account with real underlying assets costs $10000 to open. b. I don’t pay any commissions c. I can trade fractions of stocks instead of buying the whole TSLA for $230 a piece If you think about it it’s way more profitable to get into CFDs rather than buying real shares and wait for it to grow, if it will grow
