Probably they invested in * coin and it doubled the price in two days, but that is pure luck, not skills.
This is wrong, the only way to make a living and being a succesfull guy in trading is just by trading with information and with your own insticts, and of course, with NO EMOTIONS.
Dont pay money for signals or tips, they all are a waste of time and money
+1, very well said.
I would also add: forget TA and focus on quantitative analysis techniques and use scripts/semi-automated software to eliminate emotions from trading.
