Nope I disagree with this, the amount of time doesn't really affect it, for me it is the amount that counts.
You could spend less time but play with a higher amount, or you could spend more hours but spend less if you just want to enjoy.
It sounds like a superstition, for me it isn't really the amount of time but the amount of money that you spend which could lead or be the reason why they would call you a gambling addict.
You should be considering both, time and money. There's a reason they say that time is your most precious asset, as it's something you can't buy.
Many people fall into the trap of focusing on money only and end up spending long hours on something that brings them very little profit (if any), not noticing that they're effectively earning peanuts per hour.
If you consider gambling to be entertainment and therefore don't mind spending your time on it, then I guess it's fine (although not necessarily healthy).
From the statement you made, I think it's better to choose to spend less time and money, both must be balanced because as you said that it was very valuable and could not be purchased and I thought the perspective of money was the same, even though it could be sought But still, if you already have it, it is better to use it wisely, it's better. I think not a little or even most gamblers are too focused on the victory of money so they ignore the amount of time they sacrifice only for something that is completely uncertain about the final outcome of gambling.
In gambling there is always no certainty and guarantee about whether you will win or lose again as usual, and that's why we should be able to consider everything wisely, it is better not to overdo the victory in gambling because as I say there is always no certainty , so allocating a little time also with a little money is much better and I hope anyone to consider gambling is nothing more than an entertaining activity.
