OK I've had mintcoin for some time now and I've got the latest wallet 1.8, and 92k mint. The last time I saw any minting was 7th April. I know I have relatively low amount of coin but shouldn't I see more minting than that?
Well for starts, the 7th of April was only 19 days ago so you've not reached the minimum of 20 days coin age yet. Secondly, with only 92K Mint, it may take a bit more than 20 days for you to find a block. As long as you leave your wallet open and unlocked, you are going to get new coins, it may just take a bit longer than expected, but it will happen.
You misunderstand me, that was the last time I minted coins, I have had coins in my wallet since 10th March 2014. I had 3 minting transactions on 7th April. But nothing since that.
No, I did not misunderstand you, you said the last time you saw your wallet mint new coins was the 7th of April, I explained that it was only 19 days ago.
Now you tell me that you had three mintings on the 7th of April and none since. Those three mintings would have been for different sets of "coin age" of coins in your wallet, and seeing as they all happened on the same day, then you will have to wait at least 20 days from the 7th of April to be able to mint again. Once your wallet mints again, they will almost certainly be in three transactions just like before.
You have to also remember that minting is not guaranteed to happen "Exactly" on the 20th day, because your wallet is acting as a "Solo Mining Rig" and has to actually mine new blocks of coins, just the same as if you had a mining rig trying to find blocks of coins.
Another thing, is that it is very advisable, that once your coin age reaches the 20 day period, and you want to mint coins, leave your wallet open and unlocked until it does mint new coins. Don't just open it and see that it's not minted any and think something is wrong, allow it to do the work needed to mint coins.
