The most bitcoin I ever had was 33 BTC which I earned after 4 days straight of gambling in 2015 between Just-Dice and PrimeDice.  I cashed out around 6 BTC and on my way to the bank to cash out the rest of the 26 BTC I busted them lol

It may sounds bad, but if you consider the fact that I started with less than 0.05 BTC then you will realize I still finished well.
