Something isnt right in here. Romania does not look like to be a very rich country, and all of a sudden its casino makes such a generous move. Even paid to blocked accounts? Wasnt Romania a country where illegal schemes or scam were popular? For me this story looks more like a money laundering scheme, then generous casino. Made thousands accounts, withdrew money, told everyone that it was a glitch. Would not be a miracle if that casino has or had tax debts, but now announced bankruptcy.
From what I've read, this is a casino that has been operating for many years, and this kind of activity isn't something they'll lose out on. On the contrary, it gains a lot of attention. More than 50% of those people who were paid continued playing at the casino and will lose all their winnings. The casino knows this. If you ask many people who play how often they withdraw and never deposit money back into the casino, you'll see that the answer will shock you. They'll say that after withdrawing, they don't stay for many days before depositing money back, playing, and losing everything.
That's true, just give the casino more little time to recover form all these, because people will still have reasons to gamble, they cant hold it enough for long, while only a few number of the winners will be able to achieve doing something tangible with the money, like investing with it, at the end, they will still use money to continue gambling and some cant be predicted on the amount of money they can use in gambling, not for a day, but over time as a continuous process, they will surely recover as long as we often lose more than we win in gambling.
