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?
the future of cryptocurrency will certainly be good, and I don't believe that altcoin takes 2 years to recover and have a future. it might happen in some altcoins but not all altcoins will experience that, 2 years is a very long time.
no one know the future but i think two years is long enough to recover and to developing, there is a lot of possibility, in next 2 years crypto could be better or stay the same just like now, there is no guarantee
the development happens on the Altcoin continue to experience increased the received many more advances that have made it a coin which is able to compete with Bitcoin going forward, I can predict for Altcoin two years will be training requirements.
