The coin is now a potential coin, because we know that the popularity of the coin will still continue to be an option for investment in 2018. of these 8 coins may be used as an option for prospective investors.
I wonder why bitcoin will be coming 4th on that list anyway, but in a way, everyone will always have their own opinion and how they see things. It is not a bad list at all, considering that most of the coins listed there have great potentials and they are obviously coins with great potentials even though we cannot actually tell what the future holds for anything at all.
However, when it comes to long term investment, I will rather tend more towards bitcoin and maybe some Ethereum and Cardano. Nonetheless, we are all just playing the card, but have no future what the future is going to be dealing us.
