I think the best altcoin for next year's investments such as eth, xrp, wave, and ltc have shown increased progress with excellent price fluctuations that attract investors and traders to use the coins in their business transactions.

Last two months on these coins there were no big moves up, I think they will be replaced by more modern

Still on the top of  my list are etheruem i believe it has a huge potential to reach x10 of its present value and maybe overtake bitcoin in the near future.the second one are waves despite the slow growth this past few months it still have room for one of the promising coin in the market..i also keep on eye on nexuim and deep coin..i believe it will have a better growth this coming year.

+1 for DeepOnion. This coin is one of best marketed coin by signatures spaces. You see it everywhere in bitcointalk threads

Mainly sticking with BTC, but also getting in Golem(GNT), OmiseGO(OMG), considering ETH. Im teying to keep up with new annoucments I feel like sth big is coming up. Like crypto 2.0. Good luck guys.

In my experience don't go with coin launched before 3 years or is not in the market for atleast 3 months.
Look for it's prospectus and community.
Ethereum was a best buy in 2016.
