Even though I lost ~$500 here and I'm sure others lost many more, the biggest bummer here is that NiceHash is/was a great idea and service that will be forever tarnished.
I didn't lose a penny of cash as a seller, but hash buyers did.
Glad I didn't trust them to use their wallet system - those are the ones who'd really get burned by this, if NH can't recover.
They really need to lower the minimum payout limit, or set that you can pay out e.g. every two weeks.
