i think it is possible. although i have never tested this but i believe that with a strategy like martingale if you start from a very small bet size and have a very huge bankroll you can win and beat the house.
That's impossible, No matter how big your coins, you'll lossing/beaten by house edge. Martinshit is the worst startegy ever, if you want to try, put your 1 btc on a gambling site and set your base bet from 1 satoshi then.
