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?
The battle between Ethereum and Bitcoin will last forever as it seems to me now
But it is great we have choice and two so good concurents here
