My first trading time it happens that you suddenly get big profits so you start quickly without realizing it. I first started trading by watching a YouTube video but it was a loss then I practiced trading from this forum and got many ideas. But beginners always make the mistake that they rush into trading after seeing the basic profit amount of the second person which results in their losses being high so in my opinion one should not be too hasty with the first time trading.
Watching is a YouTube Video for the trading without proper knowledge about the trading and without the proper strategy following is of no use. This can only give you a less information about the trading but loss will be there and also risk will be on peak. First time trading is always difficult in a sense as the person didn't appear before in the trading mechanism so the adjustment of the trading strategies would be tough for him as always during the first some days or even months of his trading.
Then with time to time he learns something from his mentors that how could I get profit in what ways I have to take entries in different coins and how could be better to take profit from different sides? etc.
