this is just personal thinking, I am very sure steem will become the main Crypto of the future, although china and Arab two countries that have great influence in the world using Ripple
What is my main reason for that, since steem is available to everyone from where it comes from and how it exists, and also to the present of the steem wallet, in the social mesia steemit has well-accounted security
I think everyone is need for the two reasons I mentioned above, but for now I have not invested in steem, my reason is that for now I work with daily wages in steemit media, but I will definitely invest in steemi, in time it
Countries like Ripple because it has an owner. It is centralized. So, therefore they can control it. Steem and other crypto currencies cannot be controlled. Governments do not like things they cannot control.
I have not learned about Ripple, but I see in market vip indonesia Ripple is still affected by up and down Bitcoin, that means Ripple is also not an independent coin
If the government wants a coin that they can control, the government can use steem by signing up into a witness steem, so every country listed as a witness steem they can control it together
But if there is only one single currency in the world, it also will not be good because there is no market competition, it's all just my personal thoughts
