Before start the listing it is necessary to develop ecosystem of the project. It is necessary that many people will use antivirus Romad and pay for antivirus it tokens. It must be demand in the tokens. Only in such thing the price of the tokens will grow.
Very often when project start listing of tokens the price of the tokens falls because project does not have a developmed ecosystem.
I think that summer is not the most successful time for a listing. During the last month Bitcoin lost 7% of price, Ethereum lost 30%. Some of altcoins lost much more in price. I hope in autumn market will start to recovery and cryptocurrency will start to raise.
Of course I would like to believe that autumn will revive the market altcoins, but many altcoins are unlikely to come to life. And the price after listing falls sharply more due to the fact that everyone starts to sell them. If not sold , and kept , then the profit would have been.
Usually bounty hunters start to sell tokens and the price of the tokens falls. Investors see that price of the tokens fall and start to sell tokens too not to lose all the money.
