That will be up to them because if they think that they can increase the token amount by gambling, they will do that and try that. But they should be careful that what they want will not always happen so they must aware of that and allocate some money to gamble.
When we gamble with real crypto like Bitcoin or USD, we set a target in a session and once we reach that target, usually we withdraw that fund. I believe you will agree with me on this point. But when we play with the token, even if we set a target, we cannot withdraw the token once we reach our target, which leads us to play a little more and I am sure you know that excessive gambling is risky.
Once someone gamble more than the limit, there is a chance they are going to end up losing their money, in this case, we are talking about token. That is why I said that people should not gamble with their mined tokens. I hope this make some sense.
