I lost 40 bitcoins, so it works perfectly

Man... you used "the system" in the roullette. I've to say "sorry, but «the system» doesn't work". Not online and not on real casinos. Loose and double up = loose^2. Luckily it was bitcoins, if it were Euros or USD would be much worse.

Put things this way: If «the system», be it on the roullette or blackjack, would work casinos would bankrupt. But "the system" has a big "hole", as you loose you double up, but if you start with 1 and loose 10 times in a row you would be loosing 1+2+4+8+16+32+64+128+256+512 = 1023, and would need to find 1024 for the next bet.
To make it "worse", machines are programmed to let win according to the casino's bank. This means if the casino has waged 1000 and, like mine, is set to pay up 98% (and this is pretty much, taken regular casinos pay up 80 to 85%), there's no way somebody will win a hand over 980. Ok, in your case you already put the bank 98% of 1023, but meanwhile someone playing on the slots just get 100, this means the bank got 100 short.
And then you have the "winning coefficient", it exists to prevent a single player from take the whole bank at once - which would leave the other players with nothing left to be won. This secondary system is set for 70% - means per hand at maximum you may wage 70% of the whole casino's bank.
In fact, in the casino, players play against each others leaving some margin to the house, nobody plays against the house.
Anyway, as I manually fed the bank with my own BC, here's the statistics so far:
TOTAL PROFIT: -493.53
