At first, I thought that I can earn money in just short period of time if I will follow the signals but I find a wise mentor who taught me to not believe to those groups because they are just scammers.
You don't need a wise mentor to figure out that this groups are just taking your money if you subscribe to those paid signal groups. They are the one who earns more money than those who subscribe to their services. Too bad noobs tend to fall prey to this kind of groups because they think its a short cut to earn money in trading.
Having proper knowledge can help us to avoid and ignore those pumps and dumps and groups.
Knowledge is not the only key to earning more money in trading, its more on timing and some luck. You need to buy or sell the right coin at the right time.
