Personally, I speak highly of Etherium. Ether is well on its way to become the standard in decentralized applications among cryptocurrencies, used by many giant corporations. It is hard to calculate the demand and future usage. The finance sector is where Ethereum offers major value. That sector has a huge potential. From that perspective, it is really fair to say that Ethereum’s usage in decentralized blockchain applications will go up 20 to 30 fold over the next 5 to 7 years.
