I think it is more about strategy over how much people gamble. For example a guy could play with 1 bitcoin but if he wins too many times in a row he will want to drop it to 1 satoshi to hit that red eventually and then go back.
Of course, 1 bitcoin is a big example and nobody who gambles 1 bitcoin would mind between 10 satoshi and 1 satoshi, but people who gamble for low numbers like lets say 50-100 satoshi each bet, those people will want under 10 to do those strategic reds, if you hit 5-6 greens in a row you go bare minimum in order to get that red and when you hit the red you continue a bit more to see how reddish it looks and after you hit couple reds in a row you go back to regular size bets. Hitting 50-100 satoshi per bet is not bad and of course nobody has to take 10 satoshi minimum out but I just wanted to share the reason why people do that.
Regardless which strategy you use, the house is likely to win in the long run, because of that there's pretty much no point in strategizing.
Just go hard and have fun, don't risk more than you can afford and keep it stress-free. If gambling starts stressing you out, then you know you've lost too much and it's time for a break.
I play games that have a fun element to them, that way it's more rewarding.
