Steem and BitShares are blockchain brothers, born from Dan Larimer's lifelong mission to secure life, liberty and property for all. Steem and BitShares are now surpassing their all time highs and competing for the top spot as the most valuable chain.
Steem
Steem has the advantage of being a social media platform that produces high value content that automatically draws in users and investors even from beyond the cryptocurrency space. This has caused a viral effect for Steemit, reflected in the website being ranked < #10000 globally.
BitShares
BitShares has the advantage of being a decentralized exchange that allows for trading of many different assets, enabling it to compete with major financial institutions and take on trillion-dollar markets like the derivatives-market. This is reflected in assets like bitUSD/bitGOLD that exist as genuine cryptocurrencies while tracking the respective values of USD/gold.
Conclusion
Both Steem and BitShares are good candidates for being billion dollar blockchains for different reasons. Their underlying technologies will allow them to scale to a global level, and they are backed by a pioneering and growing Graphene community of visionaries, developers, and entrepreneurs.
