Here are some tough days for Yolo dice investors. 10 days I am constantly negative there. I have only Doge investment.
Same here.

All of these investments are doge. Someone is really going high and is very lucky. I guess a whale is doing martingale stuff because my wallet shrinks day after day. Hope to see him hitting killing strike soon

The wager size of that player is the main issue on that negative profit of yours. Martingale method will not gonna be effective in the long run if the player has a small wager capacity because at the end, he will surely lose overtime because he can't sustain the game due to his limited balance. There is no way that a low wager size player can give a negative profit to a casino unless he is playing it wisely with enough wager size to beat the house.
