I almost lost all my Bitcoins today lol never again
I did $100 bets and end up losing $800
then I was in real Tilt and bet 70% chance on $1500 2 times
and win $400 2 times.
So at the end of the day you are even but you risked $1600. You could even lose those $1500 too which could led you $1600 loss in total. Would you then go for $3200 worth of stake (assuming odd is 2.00 this time) and if failed then a stake of $6400 and keep going?
Please do not chase in gambling. You will not be lucky always.
