Both of these offer different advantages:
Bitcoin is the safest cryptocurrency and has reached the widest audience.
Not to mention holding a third of the entire market's value.
Ethereum is right there with it, holding second place on the ranks.
DApps, DAOs, and Smart Contracts changed the game.
So where do you bet your chips?
BTC or ETH?
Ethereum team is working constantly in its improvement, and as prove of this, they are changing now the consensus protocol from pow to pos. What I mean is Ethereum has a constantly team working in the areas. Unlike Bitcoin, unfortunately is taking only for speculation and trading, though Satoshi created this one for electronics payments, we all now is not so, it is using more to make trading or to hold but less for the main purpose.

according to private, I prefer Ethereum. but I see from the price and its development, Ethereum is still under Bitcoin. I want to follow my heart, but I also want to think logic. that I should have chosen Bitcoin which is clearly visible from the price and its development.
