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?
I will bet for ETH for sure, ETH is a very good choice for a long-term investment, so i will choose ETH for sure, i really think ETH can reach $2k soon, it will really happen about in 2019 or 2020, BTC will still maintain its position at this rate, but ETH will catch up BTC soon
