Hi @steembusiness,
I do not think age is a factor when it comes to Warren Buffet making claims that Cryptocurrencies are not a "productive asset". Furthermore, I do not think we should dismiss his mental horsepower, the advisors he has to hand and personal experience in and understanding of finance and say he does not understand Bitcoin just because this is a ‘new and disruptive area’.
It is merely a fact that cryptocurrencies in themselves are not 'productive asset' beyond the mere speculation which gives it its price.
However, the underlying technology 'Blockchain' when fully deployed is most definitely a value-generating asset as it has the potential for executing asset transfers and storing transactions and contracts. Blockchain (not the cryptocurrency itself) implemented in various industries can add value for example by changing transaction, information flow and business processes, reduce costs and in the long term potentially change the way we think about organisations themselves. Blockchain compared to a standard Cryptocurrency is most definitely a ‘productive or value-generating asset’.
I hope this makes sense?
Best Regards,
