bitcoin mining is good and can make some profits from it and No for newbie.
Bitcoin mining isn't profitable either for the far majority of the people, so it's pointless even mentioning that. The only entities managing to make actual profit are those with hundreds of thousands worth of equipment at minimum, and even they need to invest in more gear from time to time. If you don't upgrade your gear, the increasing difficulty will make sure there is no point in keeping your operations running any longer. People for once should understand to put mining aside completely, because it doesn't bring you anywhere -- the far majority of the people regret having invested into anything that's mining related, so why continue to go through all this?
