Yes with same amount of bitcoin you can play poker longer then other games, I also play micro cash games at betcoin.ag 0.01/0.02 or 0.02/0.04 and 0.05/0.1 mbtc. Before I often played 0.1/0.25 mbtc but now that is too expensive for me and my bankroll, but when I get in some money I will get back to it.
Its not good to be upset when you gamble, poker can be annoying sometimes but staying calm and patience to wait you hand is crucial if you wish to make profit in long run. Come to betcoin.ag and lets play together, see you on the table my nick is Underworld.
