$20 is 10 buyin,so the answer is no ,you need at least 20 buyin that is $40.
I deposited $20 to start play, this bankroll its enough to play a cash holdem $2?
According to this, a US$10 bankroll will be very little? Because to have 20 buyins with that amount you´ll need to play everyone of US$0.50 and if so, you´ll need to play just sit and go and no tournaments?
You can by playing sngs or double or nothing with micro buy-in such as $0.25 or $0.50 with 9,18 or 45 players and try to build up your bankroll from there.Bigger field tournaments you need at least 75 buy-in.
Like if you can't afford $20 you really shouldn't be playing online poker
