Changing ETH -> BTC so i dont think its liquidity problem.
I'll wait for answer, i dont think the pool would work for long time with out operator.
EDIT: Tested auto-exchange to ltc and its working (for new mined coins), only now i have some "old" eth on exchange.
It's hard to say if there's an operator, certainly nothing visible. If not then wallets wouldn't be updated and mining would start
to fail on coins as the wallets become obsolete.
Most complaints are exchange related and it's hard to say if they ever got resolved or if the users just gave up.
Crypto exchanges have never been reliable, they pop up and disappear regularly. Eth<->BTC should be the easiest trade
to make so, you're right, this isn't a liquidity problem.
Regardless, isn't it time people started mining elsewhere with MPH having such poor or non-existant support?
