Do you use Google? Facebook? Amazon? Netflix? Spotify? Skype? Other internet services? I am guessing that you use some of these companies' services and many more others besides? These are internet services with a real good purpose.

When you or your friends and family start to use blockchain services, for uses other than hoping someone will pay more for their tokens than they paid for them, then you have found blockchain with a real good purpose.

I would appreciate if you could let me know when this happens :)
