Martin gale will work on small ammounts on a big balance. Just quit whilst you're ahead and don't get greedy.
Not really, you can also bust on the first few rounds, even if you have a big balance, the risk is actually higher here.
This gambling system works so that you must take ever escalating risks to potentially receive a small reward that does not increase with your increased risk.
It isn't worth is to use 1BTC to get 1 satoshi. If you actually want to use it to make a decent profit, example, 0.01, you can bust within the first few rounds, variance occurs so you might get a very bad streak immediately.
But you won't just win 1 satoshi. You could start betting 1 satoshi each time but if you've got a 1btc balance eventually you'll have a big loosing streak and eventually win where you make a little profit. Rinse and repeat.
I know the odds and I didn't say it was foolproof. You're unlikely to hit 23 loses for a while and obviously you take the gamble that this wont happen on your first rounds. Get greedy and gamble all day and you'll most certainly lose out.
2^23 and that 1BTC is gone. It most likely won't happen on the first bet, but it very well could. The fact you fail to understand odds is saddening. Whatever the final exit limit is can be calculated at 2^(X-1) - X is the number of times you can fail before loosing everything.
This is the reason casinos have table limits to keep absurdity out.
