I would recommend Project Hydro. It has huge clients involved in this project and is only under 13.98 million market cap as of writing.
They have huge clients and partners namely T.D bank, Principal and CI Investments and many smaller ones but not insignificant. The team has also hinted that they have just partnered with two of the biggest tech companies in the world. Tho there is no official news announced (except for google cloud) by the team yet, some community members have been diligent in their research and found that IBM has added Hydrogens APIs into their cloud services. Another finding includes Oracle adding Hydrogen as a silver partner. A newly posted article by the Co-founder, CEO himself that sums up the year 2018 for Hydro is found here, which showed Oracle and IBM as new additions to the Hydrogen ecosystem. Hydrogen has added over two dozen new collaborators to the ecosystem, including Oracle, IBM, Google Cloud, eight fintech hubs globally, four global consulting firms, some of the most prestigious blockchain projects, and top European fintech incubator LHoFT.
In brief, Hydro it is a decentralized, open-sourced project curated by the Hydrogen Platform Corporation based in New York City. There are various protocols and APIs that are developed and being developed, by the team and by the community. These APIs and protocols are 100% free and accessible. Hydro tokens are the native tokens of the Hydrogen platform which are already listed in these exchange (Bittrex, Upbit, Bitforex, Coinex, etc.)
Secondly, Hydrogen is a startup which is profitable in the year 2018 and we are all aware that it is the year where crypto entered a bear market. Many Crypto or blockchain related companies ceased operations in 2018, but Hydrogen remained profitable. They will release an annual financial report once everything is fully finalized.
Thirdly it has multiple products & whitepapers which differentiate itself from other crypto investments. One of their products named Raindrop is already live on the Appstore and Playstore. Raindrop is similar to MFA (multi-factor authentication) but it is completely decentralized. Other various protocols that are still being built are Snowflake, Ice, Tide, Mist, and Hail (recently added). The rest of the protocols are still in development, which makes Hydro a big opportunity to invest in. Q1 2019 will release the much-anticipated dAppstore followed by ICE, TIDE, MIST & HAIL. The roadmap for the project can be found here.
Hydrogens ecosystem consists of many parts covering security, identity, documentation, payment system and AI. A more detailed explanation of the ecosystem can be found here, which was written by Hydrogen Ambassador, Mark Anstead.
Hydro hopes to create a worldwide ecosystem for better, simpler, fairer, more transparent, and more affordable financial products. Hydrogen will create a new digital economy that will uplift and empower an emergent middle class, bringing Financial Technology to the masses.
