I think the crypto is wold main economical point in 2020 !
Yes, crypto is our future currency, I am sure, but everything will be not so soon as you write about it. I do not believe that 2020 will be the year of a real cryptocurrencies progress.
It can happen even later, but I hope, we will see it. The cryptocurrencies will be used everywhere in the future. Even those people, who are very skeptical about Bitcoin and cryptos will accept them.
