The best ICO to invest will be Blockchain services in my opinion:

Phantasma Protocol (Blockchain) - Next-generation messaging protocol, using the power of the NEO blockchain. Decentralized, fast and secure.

PCHAIN (Blockchain) - The first native multi-chain system that supports EVM in the world. Making large-scale block-chain applications possible.

Kambria (Blockchain Service) - Decentralized open robotics platform to accelerate the development and adoption of impactful robots.

Atonomi (Blockchain Service) - Atonomi provides a new security protocol and infrastructure to enable billions of IoT devices to have trusted interoperability for both data and commerce.
