Analysis only helps you to make profit in the short term. To be able to profit 50-100 times, you first need to hold it in the long term. Then you need to be patient and wait, in addition there will not be so many altcoins in this market, depending on your luck.
Technical analysis also helps in long-term investments, but you cannot rely only on technical analysis. fundamental analysis is just as important and needs to be constantly updated based on price movements
