It is true that there is a distinction between the blockchain and cryptocurrency, but to suggest that cryptocurrencies will disappear is not a very intelligent statement, there is no better way of tokenizing an asset than the blockchain and that creates your crypto, increasingly being supported by more businesses,we are going to have more of cryptos
For me,i believe that cryptocurrency will have its own time to vanish but it might happen maybe hundred years from now.Cryptocurrency will still be more popular few years from now and in fact,some of the governments are starting to adopt bitcoin as a cryptocurrency so hopefully,more countries will start to see the potentials of cryptos too.As long as blockchain is still present,then cryptos will surely go along with it too.
Yes it's true, most of the countries now are starting to accepts the large accomplishment and potentials of crypto currencies. Also blockchain have a large paper currently so I believe that crypto currencies were not disappear sooner or later. I guess it will run unto second, third, forth or fifth generation, I was looking forward that all people were not use paper money instead crypto.
