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.
When the developers leave then there is no future for the coins except bitcoin because we push that bitcoin is the best cryptocurrency type. And it depends on the developers, if developers are serious to develop their project then many people will come to buy their coins
