That might be true. But I do not believe Ethereum will be able to hold their gains for long. Sooner or later the price has to go down simply because that is what markets do.
So always remind yourself not to get lost in the mania and try to stay objective. In a market like this, it is easy to think that the good days will never end.
I think bitcoin would be number one for so long because many people are happy with bitcoin and are supporting bitcoin. I thought for sure it would take until the end of 2018 but it looks like this summer ethereum might pass it up. With the turmoil around BTC potential splitting, it might be very soon. IMO this is healthy, we will always value bitcoin for being the one that started it all, but it's time for a more dynamic and adaptable currency to take the lead.
