Martingale does not work! 
Stop trusting all those bots who Claim to make you rich.
mostly you have a Chance to win: 49,95%  
That means that you need 1000 attempts to make 495 Satoshi Profit
But the Chance to fail is ( with start capital: 1000 Satoshi )
1+2+4+8+16+32+64+128+256   or 0,4995* 0,4995 ... abot 0,18 % 
so after 500-600 attempts you are busted! :D
