Why do you think this is a scam? After all, they informed all players by e-mail that they were closing only temporarily. Everyone can withdraw their money. In my opinion, this is a sign of honesty and not an attempt of any cheating.
Don't trust account that will just post without any concrete evidence and also checking His trust page you can assess if he is telling the truth or not.
After a while I realized that it must be a troll or someone who wants to damage good opinion of luckyfish.io
Everyone can see that luckyfish behave honestly and informed its users on time about all changes. There are no issues with withdrawals and this is best way to build trust of the casino.
I hope the update will be without problems as well.
