There may be a lot of consideration and analysis that must be done to decide to mine a coin. Frankly, I would rather be a trader than a miner because mining requires a lot of capital for equipment. I also have litecoin, but not as much as I have bitcoin, ethereum, BNB and Solana
Yeah, it depends of your situation, each one is different. If you bought enough ASICs at a fair price and already own the infrastructure/power capacity, it won't be the same as someone starting and entering in the business today. I would not start to mine from 0 today to be honest, coins difficulty is high, electricity more and more expensive on my continent, but as long as I make profit I will continue.
In the case of LTC/scrypt algo coins, my ASICs paid for themselves already, so it is okay to hold most of the coins now. I am not enough patient to learn how to efficiently daily trade, I don't have the necessary skills, in my case it would be very risky lol.
