You're right, he can consider that as a means to have his coins on hodl just that there may not be any opportunity for it to increase over time should incase of bullrun, they will still maintain giving him his exact amount of money worth in crypto, but the good side of it all is that he is lucky as well to receive a positive response from the team that his fund will be released after 48 weeks, what if he sent to a blocked down account and loose the entire money in vain, some silly mistakes could cost alot and enranged more anger, but i still see him being lucky with hope for restoration.
funds due to some accidentally making out some deposit rather than on losing it completely and its true that he's still really that lucky that the casino he had been dealing with is really making out some clarifications that the funds are still intact and he could only access those amounts on the time where the exclusions would end which i could say that it is really indeed still that fine and as same as you said that it turns out that
it becomes a holding thing where 1 year time then you dont know on what would be the price of coin on that particular time.
Looking into that ETH deposit which is 3 coins then we do assume that guy does really have lots of coins which he is really just tending to gamble a few thousands.Its true that when the time comes
where prices starts to cling up then he would be finding for it to be worth and would be not get stressed that much on what he had committed when it comes to that mistake.
For now the best thing to do is to forget and move on and would just withdraw on the time that self exclusion expires.
