Every time losing with Martingale I blame myself and promise never use it again.
But...

Martingale is a poison.
Someone cares to explain what even that martingale is?
example :
You're betting
BTC0.0012 ->
loseYou're betting
BTC0.0024 ->
loseYou're betting
BTC0.0048 ->
loseYou're betting
BTC0.0096 ->
loseYou're betting
BTC0.0192 ->
you won this is how the martiangle works
and you get
0.0012 profit because of this martiangle
you make .0012 and risk over .03BTC, over 30x what you're looking at winning and that's only over 5 losses. People run into 10, 15, and sometimes even 20 loss streaks and people have the nerve to use the martingale system.
