I would only gamble for the profit you can make with gambling and if you are rich the fun is gone of that.
Well what is the only reason why people gamble? There are actually 2 reasons.
First one is for entertainment which is a legitament reason.
Second is for monetary purposes, which is a very bad reason unless you are highly talented and skilled and can count cards, etc.
if you were rich you could use some strategies that are not working for you now because of limited funds but in case of being rich that is not a problem anymore.
for example a strategy like martingale need a lot of funds to be successful and a huge bankroll can still win even with a lot of red.
