Trading just like gamble but we can predict the result rather easier than gambling ( when you actively spend on forum and news )
Just make sure that you're have trust that altcoin or you will got scam ( altcoin are more risky than bitcoin )
I do not think trade is like gambling, it is the wrong thinking of many traders at the present time. we can use our own analytical approach to evaluate an altcoin in the crypto market and thus decide whether or not to invest.
Most fake news, FUD and Fomo are many. So the risk is very high when the news is fake. We should go in the opposite direction of the crowd, which will help us to be more profitable and pioneers.
Knowledge is very important. This is like entering into any profession without any knowledge and saying that it is unpredictable. Like - you start building a house without any design project or basic knowledge and you never know when it falls down in pieces. Of course you need some basic knowledge and you need to stay informed about the current market affairs. But this is normal for any profession you choose. I do not see any reason for concern here.
