When Ethereum came out, it was looked down upon because the market hadnt matured yet. No one understood much about cryptos beyond the peer to peer transfer. When the difference between Bitcoin and Ethereum was established, that is when we had a surge of the altcoin rush. This caused prices to skyrocket on all altcoins. It seems as if the roles have been reversed and there is more doubt on Bitcoin than anything else. This is why we recommend you hodl Ethereum over Bitcoin.

Just because it is down 2% less than Bitcoin doesn't mean it is some kind of amazing investment that should be observed as the next big thing for cryptos in general. It's not going to be anything special and it still relies on Bitcoin when it comes to the graph tracks that it has. When Bitcoin dips, Ethereum will dip right along with it, along with every other crypto aside from a few rare exceptions. It doesn't seem to have the kind of independence required for being a "stronk crypto" that everyone should hold, now does it?
