What is the future of cryptocurrencies ?
Cryptocurrencies that will work will go to the ones that people can use to purchase things. As a result we have yet to have a crypto that allows you to buy things as easy as Visa or Union Pay . Frankly the big companies bringing out new currencies will win. Facebook, Amazon, Tencent etc. Now for crypto assets (like Bitcoin and its derivatives) there is a need for easy ways to park your money and to have an asset that is not subject to national currencies fluctuations. I beleive those will continue to be around. Bitcoin in my opinion is an asset, not a currency. In fact until you can but a cup of coffee/meal everywhere worldwide, I don't beleive any of these are currencies. I like Edward Snowdens comment that really sums these crypto currencies up well "Proof of Work as an environmentally destructive activity slanted in favour of the rich, and Proof of Stake as a direct handout to the rich in the hope that their greed will keep the system running." Blockchain as a development pattern will continue to flourish as a way of reducing layers of approval in many areas like supply chain, banking etc.
