How do you choose when to change the cryptocrreuncy you mine, if you can mine multiple cryptos ? I mean, how often do you that ?
When the current coin isn't giving you a good enough profit, I can move to other coins in a week even a day, it depends on the situation. You should have own calculations to decide when you need to move to the other coins.
I've never use multipool or Algo switching, I do it manually.
