Honestly, in trading i'm pure gamble. I have zero experience in analysis and sometimes only ask my friend what coin that he bought or maybe do future trading in which coin. Coins that i bought myself usually only BTC, ETH, or BNB which i will hold for longer time and sell when get a little profit.
That's too risky especially in trading, we should have our own analysis to fully understand the market and this makes you more profitable.
In terms of predicting the market price, it is still not sure even if you do your analysis because cryptomarket is very volatile and if you're going to predict the price of shitcoins, that's pure gambling because no one predicted that price accurately, its about hype for every shitcoins, they are just scalpers for sure.
