I Like the cautious approach.
But there are some Alternative blockchains that have innate business models.
Personal information is a big issue these with Facebook scandal.
There are a few blockchain platforms dealing with personal information trading and credit scoring.
Algebraix, bloom, civic, MyCreditChain.. All of them are interesting.
HUGE fan of algebraix, especially since they're focused in the advertising space. I love the fact that I can earn crypto by watching ads. this even bridges the gap for advertisers. A win-win in my eyes
