martingale

only works in the short term and is not recommended to play too long, because in the end you will still lose

I try to martingale in jackpotracer, i can make 0.002 to 0.019 btc
but its all lose because im greedy still running the bot
yeah greed always make us lose everything, you should have a target such as a stop when it reaches 0.01
BTC, then you play back with a capital of 0.002

I dont know if i greedy, i just want to more profit and always run the bot,
i change the account and try again with capital 0.002btc and same strategy but not happaned again

Bots don't work in the long term unless you are very lucky. Bots do work in the short term, but usually not in the long term. If you want to make a profit, I suggest you choose a different method that's not gambling.
