Losing more. I realized there's no strategy that can consistently work. If you're in losing streak and your funds are already drain, then it's time to quit. Don't ever try to deposit again just to chase back what you've lost because you'll only regret it.
Your realisation is correct; there is not a perfect strategy that will guarantee winning back what has been lost to gambling. The best strategy at that time to adhere to is to quit gambling for that day and not to make any further bets, as it will result in losing more, adding to the already lost one, because once our mood is affected, the type of gambling judgement we will make will be harsh, and the end result will always turn out to be negative.
Yes, there is none and there will never be any as long as we make gambling the context of the discussion, and that is the reason why a gambler must always apply limits and be responsible because there is no certainty that you will win at the end of the game.
Gambling is always a risky activity and the risk will always lurk as long as we play no matter how hard we try to find a better way than others, I agree with you that the best strategy that can be done is to stop and rest when we are experiencing defeat.
We must understand that continuing the game is not a solution to restore the situation, especially if you bet with a larger amount and it has been proven that most gamblers who do it actually lose more money.
