I just tried something i have read here in this topic to give a shoot just 1 2 times and yea i was lucky i bet 0.02 and won 0.02 and make a withdraw but i dont think i am gonna do that very often 
If you really made profit of 0.02 from same amount than it is a clever move you did by withdrawing your profit. But mostly people will end up continue gambling until the lose all there money. But as you said, this game is purely luck based and we may not repeat same results if we gambling again.
but remember that this does not prove anything about the method used.
because for a gambling method to be effective, it has to work consistently. which means if anybody uses it and for "a long time" it should have the same resutls
