Actually i agree with your opinions there are many new alternatives coins failed because no investors in them, but does not mean no new alternatives coins in coming future because the real of businesses will addopt the technology of blockchain in cryptocurrencies. In my personal opinions there are many new alternatives coins were failed because of the developer of team which stoped the projects just because they did not got the investors. I have found one project event they did not got the softcap but the project is still development until today and they did not give up, it is about how to build the businesses related with cryptocurrencies and it depends on the team behind of the projects, we can not blame the great technology of cryptocurrencies.
