Coins work based on the concept of a blockchain, which links blocks/transactions together. A "fork" means that there are multiple versions of the blockchain in existence. Sometimes forks can be caused by multiple wallet versions, with people mining on different versions. In the case of IVC though, we are on the same wallet version, but the blockchain has been "forked", or diverged, from the blockchain that MintPal sees as being correct. That means that our coins are not seen as being valid by Mintpal. Unfortunately, it isn't worth the administrative overhead to maintain a small coin with problems like this, so we won't be resuming mining of IVC.
Sorry but this small coin was 0.005+ btc/mh/day from weeks
if you see all other coins is much much lower than IVC. The IVC income was the most stable in last few weeks.
If you not want to fix it is there any other pool that is on a right fork and I can continue to mine this coin?
