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.
Like what I previously mentioned in similar threads, trading involves a great amount of risk. There was this article that I read before that 97% of beginner traders lose money in their first attempt while 3% only earned as much as a bank teller.
Trading is definitely not a game as it requires capital and skill. The knowledge on the market will definitely help you arrive at a decision on whether to purchase/sell your coins but experience is what separates a trader from a skilled one. That is why, before you trade, make sure that you trade only the amount that you're willing to lose. If you are a beginner, never go all in.
