Or perhaps Bitcoin doesn't even have to be that day-to-day global currency everyone shall be using all over the world. With what's happening right now, we're once again confronted with the reality that Bitcoin simply can't perform that role. I'm reminded of Hal Finney's vision of Bitcoin becoming some sort of a "high-powered money" in the future. The genius was at least realistic in acknowledging Bitcoin's shortcomings. The Lightning Network is a development in this direction.
