you will get the same percent of profit if deposit 0.28 stakes. It will require just $4.9 as collateral. I like that most of hunters so stupid - many of them don't understand that they can deposit even 0.01 stake, get TKP, and repeat again-))
0.28 stakes will require 0.28*109$*3=91$, not 4.9$. And no you can't deposit 0.01 stake, sell for TKP and repeat because if you deposit 0.01 stake you would need 0.01*109*3=3.27$ collateral and you sell it for 0.01*109=1.09$ therefore you cannot repeat this just by depositing and selling small amounts over and over again.

Btw, let's keep this discussion clean and not call anyone names
