More and more central banks are researching the use of electronic money, they want to understand how electronic money and Blockchain technology can affect their countriesThese are the reasons why electronic money will become more popular in 2019.
I really doubt that central banks are researching because they wanted to take advantage of electronic money. What they're interested at is the technology behind it, which is blockchain. They hated crypto because its a threat to their existing financial system.
And you, What do you think about the future growth potential of electronic money?
The future looks bright. Eventhough we have seen a lot of negativity and countries becoming hostile to crypto, there will be nations who will support it because of its potential. We have seen countries enacting laws to support crypto/blockchain/ICO's. So its just a matter of time, maybe 2-5 years its full potential will be realized.
