Some things I can see are. 1. Not having to deal with currency exchange 2. Banks or Government seizing money 3. Nobody can steal bitcoin from you like a bar of gold or a bundle of cash 4. The network has proven itself to be bullet proof from hacks 5. Faster transactions 6. No inflation since Bitcoin has a fixed supply ​ Are there any points I am missing? And if this is all about the good stuff about bitcoin are there any cons to bitcoin?
