Will I get the coins I have on my accounts? or its all lost?!
I think only people who have coins below the minimum withdrawal has not been paid, others have got their coins. but you can at the sametime send a mail to them if you have not received yours.
Or he can just wait till Bitsler fully come back, hopefully soon as Baryom has said that there is new dev team who is working for the website already. I believe when the site is coming back then all balance which is under the minimum withdrawal stays on the account. No need to worry IMO, but if his issue is about not receiving withdrawal then indeed the best thing to is sending them a mail.
