What you guys think which altcoins are the best for investment purpose, mention your reasons too?
For me below are the coins which are best for investment.
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)
In your list the strongest one is of course ETH, specially because three of the others (Icn, Adx, Vsl) are projects built on the Ethereum network (Iconomi is a fund management platform, vSlice is a gaming platform and AdEx an advertisement platform), so the rely on Ethereum to be succesful.
ICN is very interesting and their platform (iconomi.net) is live and open for the public (they have just opened it earlier today).
I don't know a lot about the others, but AdEx is competing with other big advertisement projects such as the Basic Attention Token (BAT). Aeternity from what I've heard is another platform project, but I think they also used the Ethereum network to create their own token for the public ICO. I've heard some bad things about them, not sure what is true and what is not, but some people claim to have never received their ICO tokens and some are questioning the Dev team.
So, in my opinion the best in your list is still ETH followed by ICN.
