Bought script. Starts with 30k bits and I don't touch anything in script. Then I goes busted in couple of hours after 2.5k bits profit.

(You have to go back to game 1750 to see how it crash)
It will be busted after 5 series of reds. I leave it as it is and try to recover something with that what left.

Edit: That script can be found for free...
