Their prices will be based on the supply and demand of the crypto market. But you can not price them because the daily volume of the market is always changing. So before an altcoin is set up, analyze the ideas and their staff. Better will be their platform and technology. Make sure everything is fine and you can self-assess the price of a coin.
in order to do the analysis of personnel, you must initially know who to look for or who to fear. The point is that there are very few real professionals and authority, so not all companies can attend. But this still does not say anything about the negative of the company.
The other important and crucial things is the news. You should know what is happening with the coin or token you're trading. Either it is good or bad news, you can predict the price in this way.
You might also want to trade in a coin or token that has a great volume since it would not be prone to easy price manipulation.
