MasterNodes.online is a masternode comparison platform currently monitoring 39 different coins. The site is a great tool for planning masternode investments, as you get a clear overview of how the coins are performing.
The overview page gives you quick info on all the coins, such as coin price, masternode requirements (also known as collateral), annual ROI, masternode valuation etc. For each coin there’s additional advanced info such as income calculations, block monitoring, lock down status and historical data presented as nice looking simple graphs.
If you’re into masternode investments, you should drop by MasterNodes.online and take a look. The site opened in June 2017 and the devs are happy to get recommendations on how to make the service even better.
