Do not treat gambling for earning more income and don't chase your loss because it gonna be a huge trap and the best thing is always to have a gambling budget. Money management is important even this just a gamble hahahah. If you lose so much and your budget for that day is gone don't topup again or you gonna suffer more believe me I already been there.
I agree with you have said earlier about "It is best you gamble when necessary not because you want to chase your loss and win back you money" because if you want to chase and win back your money you need 10000% of luck at that time.
Well this is the proper ways but it seem gamblers aren't ready to pause after losing their deposited fund the false hope given will always make them want more no matter what and this trap is and always be a strategy to pin gamblers and get them addicted to playing it more often to win back their lost money.
Gamblers are easily tricked with little profit and it's humans has greediness , desire for more it's in out nature , Instead of taking the win and leaving with profit they tend to be smart causing them more loss than their realised profit.
A healthy approach to gambling is when you are able to start and stop at the right time, meaning gambling when you have money that you can afford to lose and stop when in certain situations such as getting a win or ending up losing, but the problem is that it is very difficult to be a typical gambler like this and most of them are gamblers who have the mindset you said which is that they are too easy to be tempted by everything they see which is basically nothing more than a temptation that has no certainty whatsoever.
Always wanting a bigger amount when they manage to get a win and not being able to accept the fact of the situation when they lose and this is a typical loser gambler who always wants to win but does not want to accept the consequences that clearly can never be avoided completely in gambling such as losing and in the end they will enter the addiction phase which will cause a lot of problems in his life, and actually whatever the situation is even if they get a win they will still not be able to cash out because they have such high confidence to encourage their greed actions which usually always end up losing again.
