Lost about 6BTC with martingale last month.

All happened in 2-3 days.

70% was due to a stupid move out of the main strategy and the rest was in a 21 loosing streak while trying to recover.

I don't gamble since that event and I'm still convinced that I can win with martingale if I never deviate from the main strategy.

This was my first attempt so I made a lot of mistakes.

Some factors to consider:

- you need a bank able to sustain 30+ loosing streaks (my second biggest failure!)

- you need to set the bot and go away

- initial bet needs to be very low which will lead to frustration if you're looking at it (this caused my main failure!)
