That's unfortunate, but not unexpected. Most of the gambler does this when their withdrawal is delayed by the casino for any reason. Perhaps, you would have lost the profits or a part of the profits by making redeposit even if your withdrawal was processed earlier (saying from my own gambling experience

). That's why
I suggested you to not play when I noticed you turned the 2.3k TRX into 6.3k TRX by placing more bets. The temptation of the profit doesn't let the gamblers to stop.
The feel is different when we lost back what we won after redeposit, at least there is a time when we manage to withdraw it first LOL.
I do believe that the reason why he keeps playing is not mainly because of the waiting time for the verfication but the temptation of making more profits gave him stronger will to bet more and more.
Maybe he wanted to make it to $1,000 but unfortunately he lost it all.
Previously
you lost $400 for the withdrawal delay, and this time the amount is almost $700. Will you continue to play at Coins.game?
It means that he does not learn from his own experience

Maybe he will continue because coins.game provide frequent promotions through email such as free spins without deposit and with deposit.
Myself can be said that I have left coins.game since few months ago, I ignored all their email although there were some FS without deposit.
