If you read my post carefully I have already mentioned that I do take occasional breaks to maintain a healthy gambling.
Gambling responsibly.
As you said, bet size plays a crucial role too. In the beginning I used to play with higher amounts but as I kept losing I realized there's no point.
So I started betting with smaller amounts and that helped me in cutting my losses.
Gambling is risky as it is a game of probabilty and your probability to win will be smaller if you bet with higher odds.
Bet with high odds is more risky, your money can be lost in toilet. If you bet with high odds and with big size play, you will have risk to lose big money in toilets quickly.
Smart gamblers will bet small enough and with small odds enough to reduce risk of loss and increase chance to win as well as keep inital bet capital safely. Like whales who win wager contests, they don't bet with high odds and big money with a few bets.
