> "No, not at present - but there will be in the future" That seems to imply that until that future arrives, people should mostly stay away from cybercurrencies.

No it does not. See my internet analogy. Asume it is the year 1993, and the WWW is just invented but there are hardly any websites. At that time, you wouldn't say that "No, there are not websites at present - but there will be in the future. Until then, stay away from the Internet". This is of course non-sensical. It is: "There is this new technology that will revolutionize everything, better get started with it early and familiarize yourself with it, the earlier the better". And yes, some people thought the internet is just a temporal phenomenon that will pass by and refused to familiarize themselves with it even after the iPhone came along.

Regarding cybercurrencies: I am myself a "bitcoin only" guy - meaining in my opinion there is bitcoin, and there is the all the rest which is shitcoin. Stay away from all the shitcoins.
