So what percentage do you think is actually real and based on serious projects?
I say 2%
as ever vitalik said , only around 2-5% altcoin that could survive in cryptocurrency market , most of devopers team have no qualification to build real blockchain technology. Today i see most project only tokenized common thing , and not specifically resolve the existing problem in market.
Because most of them are just after for the money that they will get. Not many projects can sustain their developments like ETH platform. Very few has the intentions to make and create a difference in this market. Once they encounter problem, some easily lose the motivation to move forward, mainly if they have no revolving funds. So yes, with thousands of alts in existence, only few percentage are really worth looking at.
