Yeah, and you ALWAYS end up going bankrupt in the end.

I used the doubling method to get up to 900m and then lost 8 times in a row and got cleaned. Here's a rough example of what will happen if you use this method -
Say you're staking 2m at a time and have 250m. If you double each time you'll lose, you'll go bankrupt if you lose 7 times in a row. There's a 1/128, or .78% chance of losing 7 in a row. If you want to double your money, to 500m, you'd have to win 2m 125 times, and since you only have to lose *once* to lose everything, there's a 125/128 (97%) chance you'll go bankrupt on the way. So if you wanted to double your money, you'd be much better off just staking 250m once, where there's only a 50% chance of going bankrupt.
See what I mean? Imo, maxed boxing isn't worth it, it's too much dependent on luck. I'd try rapier staking, specs off.
