Is it still worth it or is the difficultly too high?
Is mining low value coins still going on or are most resources now directed at the established GPU mined coins, albeit at much higher difficulty?
That's right, now it's much different, it will be very difficult to own a mining area where we will often get kicked out by big equipment and miners with high power and more advanced technology. It cannot be denied that when we are familiar with mining before, it is easy to get 0.1 satoshi in just a few minutes. maybe you still remember when 2014 was very, very easy.
now I don't have the interest to mine any altcoin. What I do is collect fees and put them aside for depositing on the exchange and buying altcoin there.
