Ethereum's gain (in percentage terms) is even higher than Bitcoin's during the last few days.
I am sure a lot of people will be scratching their hands trying to find the reason.
I think the Ethereum community is more unified. The Ethereum has good development plans and implementation.
Well I have to agree that this is all because of the BTC hike. But good point here how Ethereum guys have it more together than other Cryptos, yes even BTC. This is because they are pretty much here unlike any other competition.
At the moment, the bitcoin rises faster than the Ethereum. In a few weeks, the Ethereum could rise faster.
I think there is no bubble in the Ethereum price now. Its value is underpinned by the usage and development.
