Bitcoin is a gateway crypto now. Monero and ETH are already replacing it in some areas of payment. As for Steem. It's a freaking blockchain social media with the potential to grow beyond it's current position of being content-posting website. No fees on transactions and a huge community can and will make enormous impact on the market and the whole structure of internet as well. Zappl is incoming which means more users and flow of Steem currency, because not everyone likes to blog, just like Facebook-Twitter relationship but with a much greater potential. We are still in a fetus phase and have survived what is called in economy "death valley" - which means that certain future without bubble is upon us. :) Thanks for sharing this informative content, upvoted!
