Latium is a project I also find rather interesting I could see some use for it in the growing market of freelance work. And it fills the outsourcing work niche rather nicely.
Funny you mention Latium because I was going to say the same thing. I don't do a lot of ICOs but I actually was looking for a solution similar to what it looks like Latium is provided to use for my business. Basically I'm looking to hire freelancers and pay with crypto for my business. So I know I'm actually going to be a user of their product once it hits the market.
Someone else mentioned a lot of gaming ICOs are hot right now and I like that space a lot too. It's so hard to tell with gaming ICOs what's going to stick and what is not. It's like investing in video games themselves - seems hard to pick winners.
I'll also throw out the energy space. I haven't done my due diligence on this project yet so DYOR but Envion looks pretty cool.
