It is official Nicehash got hacked https://www.justcryptonews.com/291/breaking-nicehash-has-been-hacked-50mln-missing
They have announced it on facebook, twitter, Reddit, etc , so there is no more point arguing if they were hacked or not, and they won't be back online anytime soon (if ever)...

The question is: Anyone has a good alternative to suggest?
My miners are already on alternative single coin pools, but I would prefer the BTC payout.
Thanks
