Blockchain is the world's leading software platform for digital assets. Offering the largest production blockchain platform in the world, they are using new technology to build a radically better financial system. Their software has powered over 100 million transactions and empowered users in 140 countries across the globe to transact quickly and without costly intermediaries.
They also offer tools for developers and real time transaction data for users to analyze the burgeoning digital economy.
Their wallet offers services for Bitcoins, Ethereum and Bitcoincash users. I, personally, am on this platform and use all the cryptocurrencies offered here. But my favorite is Bitcoins because of it's widespread use.
