I too agree on you understanding about tge topic.  I do not think that a single local government can ban bitcoin.  All they can do is regulate the ingoing and outgoing processes that the users of bitcoin in their country is doing. They can make rules and regulation imposing taxes on the process of converting bitcoin.

I think the best way is to invest in both, both tokens are increasing in value, but bitcoin is more stable and is increasing at a high rate and high pace, ETH is also increasing but in fairly movement and does have an unstable value, so it is ideal to invest in both and hold them as long as you want. In five years the bitcoin is still number one in the spot, but i think that the ETH could rise as half as bitcoin, with its usefulness and majority of it is use in trading.
