I usually make bets of just a few cents, so my total winnings are very small as well. I cant afford to lose dozens of dollars so quickly in the auto bet.
I tried both approaches, with lower and bigger amounts, and in the end I lost money most of the time because I didnt know when to stop 
Tell me are you using option for automatic placing bets on l0tt0 or you doing everything manually?
I started using auto-mod more when I am busy or doing multiple tasks.
