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
