Pros: 

I love earning and sharing helpful business information.

Cons: 

I need to figure out how to spend the crypto currency.

As a senior citizen I have actual experience in developing community programs and marketing. I also founded and sold a startup. 21.co let's me use what I have learned while paying me in cryprocurrency. Now I'm learning about blockchains and cryptocurrency!
