I fully trust and believe that the idea of decentralization is the best thing that can happen . Cryto-currency and the blockchain technology is one of man's smartest invention .All credit and thanks to Satoshi Nagamoto. Also, steem is one of those crypto which is likely to be the most used due to it's nature of quick easy transfers and 0 transaction fee.
Steemit is likely to outgrow other popular social medias such as facebook and twitter easily. Unless they fully embrace the whole idea of decentralization and start a rewarding system for their users to be rewarded, they are bound to fall.
Same applies to video platforms such as you-tube and messaging apps like whats-app. Dtube and Telegram will probably be their biggest competitors respectively . All the same i wouldn't be surprised to see or hear these centralized companies planning to use the blockchain technology . Telegram , Samsung and Kodak are already ahead in this.
Long live crypto and all power to the people.
