Welcome to Steemit! Any friend of voluntary social interactions is a valuable contribution to the community.
I'm glad you mentioned Bitcoin and cryptocurrencies. Crypto is doing more than anything else to enable people to live outside of the traditional regulated system and freely interact with each other economically at a more sophisticated level than barter (nothing wrong with barter, btw!)
Thank you @finpunk! 1000% agree that crypto currency & encryption in general is freeing more action than was ever possible before it's inception. Free interaction, without coercion, and without an arbitrary 3rd party bureaucracy, is undoubtedly the path to an ethical future!
