You're right - that's exactly what could happen. However, the mining server only switches coins when the amount of money that would be lost due to the reduced hashrate is less than the amount of money to be gained by switching coins.keksik wrote:hello, i have checked my miners as they report lower hash rate as they currently have and found it could be cause by switching coins too often. my rig found two shares and then switch other coin, then find another one share and again switch. let me explain. for example i have 9 GPU rig hashing 268Mhs howewer it shows on web page only 229Mhs, which is 14-15% less,which leads to less revenue. i understand there could be some stale share or orphaned,etc, so i understand 5% less,so is possible to switch coins in longer periods?
curently i havepointed here 790Mhs and it is showing only 612Mhs on webpage, thats like 1 whole rig.
Therefore, you shouldn't worry about the hashrate issue. That probably indicates that the system has found a coin with very high profitability. If you were to compare your earnings rather than your hashrate, I bet that they would be higher because of the coins being mined at the times the hashrate is lower.
Also, you might want to note that for the algorithms with more hashrate, this situation is less likely to happen because there aren't as many easy and profitable coins to mine. The algorithms referred to in this thread are new and have fewer miners, so those fewer miners can all be assigned to the most profitable coins, and the miners are able to earn a lot of money.
