Regarding the coin you've listed:

Icn (High potential to increase in near future)
Adx (Price is low from ico but price will increase soon)
Vsl  (Profitable)
Eth  (Best option to invest for long term)
Ae (not on exchange yet)

I would totally agree with you on the ETH part, to be honest most of the other coins I don't even know, but Ethereum is by far the best long-term investment. Just think of all the potential it has, it will be the main network for decentralized applications. There might not be any used at the moment, but at some point we'll be seeing people willing to use them because they will offer real value that will benefit many. And in order for these people to use these applications they'll have to buy GAS, and that will be done by buying ETH. And that's not all, when Ethereum goes to PoS everyone that will have Ether will be able to validate transactions (unlike mining) and earn a steady passive income, how awesome is that?
