I have invested in rentberry.cryptonomos.com
I think I should have gotten more than 1 ETH at 33% bonus at the time. Now I am thinking of buying more.
Why?
1. Solid company behind
2. Legit project.
3. Potential benefits for the holder. Possibly a giant market will use this coins as deposit between landlord and renters.
4. Company can still grow tremendously
This is my personal opinion based on my personal research. I really do encourage YOU to do your own research.
