At present the market is very chaotic, many coin has nothing value but the price is high. This will change after about 2 years as the time in most altcoin's roadmap is after 2 years of product launch, then the Altcoin will actually return to real value. The Altcoin is really valuable at that price will go to moon. Do you think so?
I am very interested to see the projects in a few years, which are now in the top 20. I'm sure a lot of them are empty, but they're worth a lot right now.
This has happened in the past, if you take the time to look at the market leaders of a few years ago you will find very few projects that still stand after a few years, this is one of the reasons of why people recommend that if you are going to hold coins for the long term you only hold bitcoin because that is the only coin that we are completely sure is going to survive for so much time.
