Pros
- You become your own bank, with no restrictions and parenting
- The government cannot take your money through confiscation, devaluation, and regulation, etc.
- Save money and time as cost goes towards zero for service and products and they become available digitally over the Internet
- Protection from payment fraud and identity theft
- Direct settlement (no intermediates) and direct access to markets                                                                           

Cons
- You depend on technology that works. Wars, natural catastrophes, terrorism, etc. will continue and computer systems could be down for short or long periods of time.
- You need basic skills about technology as well as access to the Internet and devices.
- Cryptocurrencies still have a way go before they can replace credit cards and traditional currencies as a tool for the global economy. The timeline for widespread use will likely be over the coming decade.
- Lack of awareness and understanding as many people do not know how cryptocurrencies work and/or are not used to using cryptocurrencies.

The best countries for hosting your web site are jurisdictions with a territorial tax / law system like Hong Kong, Singapore, Panama, Liberia, etc. These jurisdictions do not tax foreign income or interfere with the business you do overseas.           

As long as you do all your business outside the jurisdiction you should be fine.

As “crowd-based capitalism” or the “sharing economy” expands, we're taking economic activity out of institutions.

In the established old model, most economic activities were controlled by large companies and institutions like banks.

Now we have a digitally controlled model, a platform that sits between people directly. New technologies based on the blockchain and distributed network make people trust each other enough for these interactions.

The sharing economy is all about people and trust. People are once again being drawn closer together on a global scale.

This is the melding between commerce and community. You could say it is a democratization of opportunities. This will lead to more independent workers and entrepreneurs as the doorkeepers like banks and other institutions are bypassed with favor given to peer-to-peer markets.
