I was recently mining on ltc.tbdice site which is a solo type site. They only pay out when a block is found and nearly all goes straight to the miner.
I had set up a specific wallet address for this mining pool and I recently had a very small payment show up in there even though I have never gotten a block on that site.
It was about 0.00065 LTC (sorry, don't have wallet with me right now).
So is this a correct payment or maybe just a bug on that specific website? It doesn't really make sense to me. Thanks
