hi mate ...
https://chainz.cryptoid.info/ozc/ ...
always check the explorer when looking at sync and issues of the kind when it gets to this sort of level ...
you will see that someone ( zpool mainly ) mined the hell out of ozc raising the diff SO high - that the 'normal' miners need to work 10 times as hard to get to the next block ... this is why a low hashrate can affect a coin in an adverse way ... and also why we will be changing the algo in the coming months ... ozc and infx will get the same algo we are developing - which should alleviate that ...
i asked crackers ( crackfoo ) many times to take ozc and grn OFF his pool - and he disables both of the coins for a short while which we appreciate - but then enables them both back on after a month or so ...
o well ... its his pool ...
when thefarm is fully rebuilt - and the new algo implemented - we wont have this issue ...
so in answer to your question - no ... you are NOT doing nothing wrong at all ...
