We have a saying in my local language that goes something like this: "from your mouth to God's ear" in this case I'm going to say "from your typing to God's eyes" :)
What you are suggesting and prices for does different "top 10" coins would need a tremendous amount of market capitalization, and I can agree to some degree but not on all does point. I can agree that Vertcoin is very undervalued at this moment and I hope more people recognize it during 2018.
As for privacy coins you are saying NAV coin and I can agree on that part too but I've been looking at other alternatives with huge potential and I must say I'm really impressed by Deep Onion. It's relatively still young coin as it was released back in July 2017. Deep Onion is running on TOR network and has integrated feature Deep Vault in its wallet. Deep Vault allows people to store file validation credentials (hashes of files) within the blockchain. For 2018 they have goals to release Following: DeepSend for even better anonymous transactions. Vote Central for its users to control witch path Deep Onion should follow. and finally Smart Contracts :) I think that Smart Contracts will really put Deep Onion on the charts for 2018 :)
So yes I'm really excited to see what secrets 2018 holds for us but I'm 100% certain that some of coins that have been overlooked could and will surprise us all in 2018 :) So keep your eyes open people and good luck :)
Ruppy sounds interesting. But I would vote for now, cause all new icons use this network and they need neo for bounty(free coins)
