Sadly - addiction is often the answer.
I myself don’t bet everyday - or when I do it’s not a bet - but either arbitrage action or trying to move funds out of a bonus/rollover to “clean” account when I do bet more frequently during FB season.
A lot of compulsive bettors too - I was years ago. Could go literally a month without betting - would come into a nice bonus check and would go nuts betting - lose it and not bet again for a month.
Like pro traders - some gamblers HAVE to be in the market - they think so highly of their ability to make a profit that they will take unfavorable prices just to keep action. Works well until it unravels on them (it always does - you can’t bet into a market that not plus even your handicapping ability).
