Newbies are crying and selling rigs. They decided that they are top miners/traders when it was a problem to become a loser. Someone bought rigs and did nothing more, another - read more and more and more trying to increase profit and decrease expenses. Guess who of them are crying now?
Well, who? If one trader is lucky and imagines himself a trading genius, then it will end badly. The market is manipulated and no matter how much you read, if you do not have access to insider information you will eventually lose everything. As for the miners, everything is very simple.
Wow. And thats why we regularly see threads like this here. Because its too simple.
There are miners who have never bought equipment and never paid for electricity. For them, mining is always profitable. To do this, you just need to use the computing power and electricity where such a miner works. Although it is said that it is like theft.
Mining with 1 home GPU? Mining at work? First case - its not mining, second - its until this "clever" boy would be catched.
