The most profitable bitcoins I ever mined, were the ones I mined when it was unprofitable to do so.
Something to think about from someone who has been mining for 8 years now.
This makes sense
When nobody cares about mining, when blood is on the streets, there you have a nice oppo to make money.
Similar to buying low situation.
When we are surrounded by pessimism and despair, this is to time to invest. And mining is a sort of investment.
