Let's clear things up: back in this context means support. I don't see any country backing Bitcoin because there's no way to control it anyway. Some people love throwing in China numbers, but a quick research would tell you that taking control is far more complicated than that.
Ripple could absolutely be backed though, considering they're a central entity. This article is a reach though lmfao. It just assumes that China is in control of Bitcoin and that the US can counteract that by supporting Ripple. Garbage lmao.
if the coins go under the control of any of the countries, it will not create military actions to promote the coins, but will lead to their rejection by the society using cryptocurrencies. any control kills the coin, decentralization is the way to success.
