I've been following Metahash for a few months now and they are very transparent on their progress. If you're interested in their technology you can follow up with their roadmap as it's on their website.
Wallet management can be done in the official MetaGate software or with the mobile wallet MHConnect (android & iphone). Using this software you can also delegate an amount of Metahash coins (MHC) to generate a passive income. My starting point was their community website MHCZONE which is a great starting point to explore Metahash.
They are different than other blockchain projects as they have developed their own TraceChain protocol. The technology is amazing, a few key points of TraceChain are implementation of AI for a self-healing network, decentralization, low-cost, lightning fast and simplicity of use.
I'm happy they have a good base of technology so they can become a major player in the cryptocurrency space in the near future! I'm happy to be part of their positive community which I found very useful to find out more about the project!
