I think that yes, we should support altcoins. There's a lot of good ideas, which can make our world better. Also sometimes bitcoins grow very good in price and this is great
Basicaly most of us only want to get profit, we will support coin which has big potential of increasing price. ETH is better than bitcoin in term of transaction but why bitcoin still has the biggest market cap among all cryptocurrency, thats because people only thrust bitcoin, they thrust that bitcoin is the most profitable Coin. I agree to support both.
