Some miners mine, and sell immediately at the market price as soon as they have their share, I respect that, it's what 80% of miner does., most miners are just people wanting to mine for profitable coin at the moment, mine it as long as it looks profitable and switch their miner to another coin/or simply off for a time period.
My only suggestion for miner like that would be, take a look at what the project you mine are doing before mining it, look at the potential. BTC miners don't sell right away, they hold and sell when the price seems high. It is during the bear market that miner does most money if they can mine BTC without going bankrupt at low price (more share because of the miner who fled (less concurrence = more share), and they sell it when it skyrocket. Because most BTC miners are believers. That way they do far more than they would if they turned off their miner when price is down 40-60% from ATH.
So for example if price of the coin today is around 50-60cents , tomorrow it will maybe be 30 cents, and in 3 week maybe 20 cents. But If you are certain that the project will come back over 1$ and far more. If you mined during this timelaps, you will make double or more than you would have done in mining only when competition is high and price is slightly favorable.
