Almost all the best advice is on the list and I think gamblers should consider it. That would have a positive effect for gamblers in my opinion.

Dont trust the strategy 100%. Yes, strategy is the gamblers attempt to win every bet and game they play. I just think that everyone has their own way of gambling and if a gambler fully believes in strategy and risks everything on one occasion, then I am very sure they will get more harm than they might win. Although the strategy is not a prohibited effort, but if you entrust it 100% to get the victory I think you are wrong because there is no strategy that can guarantee the gambler to win at every opportunity.
