You are free to create and use multiple accounts. Balances and internal transfers between accounts are private information. However bets are public information and there's no way to hide this. But I don't see why you'd care if people snipe your bets, it's not like it changes your bet outcome or the game outcome
I dont know, maybe it's just my guesses, but yesterday I had 150 losses in a row, the game crashed before reaching my profit and would have reach at 151 time, but my balance had already ended at that time. Now Ive edited the strategy and in the morning (+5 GMT here) I have found out that some player is following me, though after some time he disappeared. I think that if two or more people earn according to one effective strategy, then most likely this will be monitored and the chance to earn decreases, although this is my guess.
