Great list.
I was keeping an eye on HPB a few months back, but as we've been in descent price-wise have held off investing. As we near the bottom I'm taking a look again.
Hold some Stratis, like the project and a bit further along than most BaaS projects... they'll need a lot of consultancy with the business world to take off. That takes time so hopefully Stratis will bear fruit once the market reverses and good news stories surface around businesses adopting blockchain.
One I'm really excited about is
Spectrecoin (
https://spectreproject.io). It's a little known POS privacy coin which as far I'm concerned has the most advance tech. Most privacy coins aren't that private but Spectrecoin protects the sender and the receiver, plus all nodes / wallets run on Tor. Best of all come Q1 2019 they should have launched Stealth Staking too. It hit $5.50 in Jan, today's price $0.22 so will do x26 just to get back to previous high.
The thing with privacy coins is the use case isn't really there yet, but when people start adopting crypto and realise their transactions are there for all to see, people will seek out privacy coins and in that battle it's the 'most private' coins that will win out.
