agrees, overestimate of cost of a coin at a stage of sales, first of all influences the future of the project, all of us observe that at entry into the exchanges or exchanges of a coin lose the cost, possibly it is one of the reasons why so many empty altcoins now.
not because after being registered in exchange they have no value. if they are trusted, of course they can grow their prices again. as long as the trade continues, there will be a possibility that prices will rise and not have a zero value. the most important thing is how the community continues to survive, it will help the growth of coins in the market.
