There are many coins to invest in long term. We have long thought of Bitcoin, but there are many other potential coins. In addition to the coins you offer to invest, you can buy cryptocurrency Dash (DASH) or ethereum. Currently, ETH is highly appreciated for being able to surpass bitcoin.
As a pos coin, Dash is a great one for long term investment and ETH is definitely the best one after choosing BTC. But eth won't be able to surpass bitcoin in the current markets. In future , it may be happened because of more adoption than the adoption rate of Bitcoin. As far from the history, not only eth's price but also other altcoin's price is mainly depend on the Bitcoin's price movement. So we just need to wait for the bull run of the Bitcoin and after that we hope to see the altcoin bull run.
