What you say is true that altcoins are still very productive. In 2019 this year I was able to earn some money from the ICO project. With the increasing price of Bitcoin, it provides a very good impact on altcoins. Some of the altcoins that I have the selling value have increased. And some ICO projects accelerate to enter in exchange.
I agree with your opinion about the ico project and if you experience a decline, of course I will save and hold for a while and it takes confidence in investing with ico
