Ive been looking at a few for long term investment, heres a few Im thinking of getting.
DeepOnion - Very good project with a solid, driven community. Has lots in the pipeline, so I expect it to rise
Cryptopium - Had a really good ICO, and has a lot of backing from financial institutions. Prob a solid buy for 2018-19
XVG Verge - Had a good run over the past few days, one to keep an eye on.
NAGA - also had an amazing ico, and have great plans to attract the masses to usage of there coin. Opens tommorow also
Substratum - Interesting one, if net neutrality stays repealed, this could take out. Basicly a decentralised internet stored on the blockchain.
Hope this helps!
