If you stop submitting shares, your average hashrate drops and so does your reward. So if you mine for 4 hours and stop, you will get paid for any blocks found within the next 24 hours, but your payments will be consecutively smaller for each block that is found. If you keep mining, your payments will remain close to the same. (depending on pool hashrate).
Sure, but isn't that exactly the problem with mining in the multipool?
Let's say I mine LTC for 4 hours straight, then your pool switches my to another coin and you switch me within the other more profitable coins, my 4 hours LTC mining is almost worthless because in these 4 hours I could have made more earnings with the other coins.
Or is this a wrong view?
It depends on whether LTC finds a block within the next 24 hours. We have around 80-100 MH on the LTC port, dedicated, so it should find 2 blocks a day on average even if the multiport is not on it.
But yes, it becomes more luck dependent if the multiport is not switching back to LTC. The LTC port has gone more than 24 hours without finding a block when the multiport wasn't on LTC, on the other hand it's also found 4 blocks in a day before without the multiport.
