fwiw, i have gone busto many times over my life....had to take months off at a time.
when i get back into it i will bet $25-$50 at a time....and it feels just as exciting as a $500 6 months before....
some guys will bet just to bet, so they can say they did it. I know a few like that who will spread $20 - $40 over 5 games. $5 here $10 if they are feeling good about the line. And then they go home telling the story of "oh yea we placed some bets on the games, drank some beers had a great time!" I would always give them a hard time about doing that, but their logic was I am going to watch the game anyway and I am not a big gambler but I will just put something on it for the fun of it. It had nothing to do with their income or whats affordable
