if anyone still reads this, don't buy an automation script or waste your time clicking.... here i will tell you how to automate the process super fast, and confirmed that you still win!

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.
Yeah I got the chests maybe 3 times on my way to 92% , and after about 50% i stopped getting anything other than minimum wins and no chests, so I agree this isn't panning out very well, but I figure ill go through another 20k spins or so, before I give up lol. And yes, my lil cheat doesn't account for chests, but I'd rather miss out on a chest, than have to click this button anymore.
