So if each company does their own crypto where convertibility and fees are a none issue would that not defeat the propose of a decentralized system. One coin that can be used among all companies would be better. This is somewhat in place with bitcoin.
I a coin has value when it can solve problems and has a platform that can integrate end users to preform tasks. Steemit is a perfect example. We all blog here and hope to earn. In the future if Amazon, Facebook, and Google accept steem for purchases would that not be the best. Thanks.
