One of the best investments right now fits your preferences perfectly - FunFair.

- they have a great team, way bigger than other crypto projects
- Jez San is a very reliable founder/leader with a good track record in the target industry (online casinos)
- the platform is already on testnet and the full release is set for Q2 2018
- basically no competition in the blockchain space, some amateurish casinos exist but this is the only online casino platform
- their tech is very respectable (see "fate channels", the only production level implementation of state channels on Ethereum)
