All Traders has a big knowledge regards in trade they never expected to win in trade cause they know that in market the cryptocurrency in trade is Volatile and everybody know that in trading is unexpected wetheir we lose or win.
Some newbie in trade and they have not enough knowledge regards in trading after that they take a risk an they just lose, all they will say that trading is a scam ,fake, not reliable, and not Good to trade. That's why they lost their faith about trading . That's why some traders here give some advice on how to trade or before you trade we must learn how to enter in trading.
This is what I often find among beginners in our country. Maybe there are too many out there. Many of the newbies who are not deep in knowledge, who are only consumed by fomo, hoaxes, they trade with ambition. Not doing the analysis first, causing them to fail and then get frustrated.
