OP, I think you should return to the old rates. No 5% or 20%, but add a bigger time, like 48 hours for 50%.

5% just ruins the fun and profitability of the game, as these people steal from the hot wallet what should be given to the people who invest more time in the game.

Just a recommendation, why don't u make the "time left" and "deposit amount" buttons which list the deposits in different ways?
