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.
I guess we can use any analysis, based on many factors, and that can give us an idea about where the price is heading! But that will not work all the time, simply new players and whales can disturb the market and push the price in the way they like, and that can be different from our plans! So it's not like there's some strategy or analysis that can help all the time, sometimes you simply need to rely on your intuition and do what you think it's the best! It's not a pure gamble if you are trading with well-known coins, but if you trading with some shitcoins, where most coins are pump and dump schemes then it is pure gambling!
