I have thought of an interesting concept which can help you out to control your gambling losses and most importantly to secure your winnings in a more sensible manner.
As poker player (with decent tournament record), crypto trader and occasional dice and slot gambler for almost 5 years I can assure you that single most important thing which can help you out in the long run is bankroll management. Although BRM is a combination of different skills but keeping your calm during loses by quitting for sometime is most important skill to master as it gives you time to reflect upon what you are doing wrong which led you to become more mature player.
It is easy to loose your mind and play outside of your bank roll in the heat of the moment. To prevent this up to some extent I propose a limited gambling escrow fund held by prestigious members of this wonderful forum.
How this will work ?
So suppose you have won a big tourney in poker or concluded a big profit trade, or accidentally (I use this word knowingly) won jackpot in slots/dice. Now what you need to do is to transfer your majority of winnings to the escrow immediately (and keep your self your normal playing bankroll). Now the escrow will have to release a certain amount of fund from your deposit to you on weekly or monthly bases. This will help you to remain under your bank roll greatly because after you loose your normal bankroll you have to wait for your next payment which will take some days. By doing this you have more time to introspect which is always good.   
I urge learned members of this wonderful forum to ponder upon this and give some suggestions to improve this.
