That is really appreciable work for having blockchain in order to serve their purpose, but this is not any healthy news for the cryptocurrency platform, I think cryptocurrency platform should reform and a set of regulation will bring back to its credibility to the people and in this way, People will use this platform for their own life, But coca-cola is just using the blockchain system for their own purpose, it's true that when Blockchain system will get popularity then people will also use this system and Cryptocurrency will also get popularity in this way, It's really a good issue that such a giant company Coca Cola is using Blockchain system, so the time is not so far where people avail this system for everyday use.
Always find for the good side of this news, and yes you mentioned regarding to blockchain it will surely drag crypto once those people who will be interested regarding to this system. The chance of adopting not only blockchain but also the crypto currency industry. Good start even it's not directly for crypto but still there's a good side if we are optimistic regarding to this industry.
