I never make spreadsheet for my gambling because I only use free money from faucet, airdrop, give away and bonus deposit. Always disciplines with rules to avoid addicted because the main problem is not about win or loss but about addicted. This problem only can reduce by disciplines and I must say also giving positive impact into my trading activity. Use gambling to train your psychology, experience and money can get at the same time.
For a person who is addicted to gambling, it would be useful to fill in the spreadsheet and specify all the amounts that he lost on gambling. Then at the end of the month, you can sum up and count how much money was irretrievably lost for the month. This can sober a person up and make them stop gambling.
For those who play very normal and not addicted to gambling, they also often do not store data on spreadsheets, so expect a gambling addict to be able to store their achievements on a spreadsheet, that would definitely not be possible when they were lacking in awareness and alert when engaging in gambling, they will never stop gambling with this method, if this method can be successfully implemented, the number of gambling addicts has decreased significantly. Another reason for not storing on a spreadsheet is that countries seem to be putting gambling on the blacklist, gambling is against the law and no one who wants to store materials can bring them to prison
This is everyone's business. Personally, I would recommend running a spreadsheet to see your results from all gambling games. It is also useful for people to realize how much money they are losing. I would not worry about the fact that your tables will be available to the authorities, there is no need to write specific names, game names, etc. and then no one will know what expenses and income you are counting.
Keeping a record of all of your losses and winnings in gambling will definitely make a gambler sobs and regret. Buy i don't think that will be enough to stop a gambler to stay away from gambling because he will still tempts to play no matter what happens as long he finds gambling as a hobby and makes him greedy.
If a person is only at the initial stage of attachment to gambling, then seeing how much money he loses in a week/month/year and comparing what useful things he could spend them on is a good cure for attachment. If a person has a serious addiction to gambling, then of course a simple calculation will not stop him.
