Apart from the fact you won't get paid at 0.03 nor you'll ever reach that sum either and to obtain consistent number of spins you have to mine and I prefer to direct my hash power toward a constant and certain source of bitcoin even if small, such as freebitcoin.in or coinpot.co miner, that said, your idea is cute but it doesn't take into account the 3 chests puzzle, but hey, I started not getting it anymore past the 0.018 balance.
