Bitcoin was invented in 2009 so by 2030 bitcoin will have existed for more than twenty years. Twenty years is a long time. The internets evolution from 1995 to 2015 was twenty years long and think about how much the world changed between 1995 and 2015.
People will be shocked by how disruptive the next seven years are going to be for finance and banking. The next seven years for bitcoin is going to be like 2000 through 2007 for the internet where we went from slow dial up modems to iphones wifi and 3G. The period from 2000 to 2007 was quite dramatic in terms of how fast things changed for the internet and those years really set the stage for the period between 2007 and today.
In the same way the next seven years for bitcoin between today and 2030 will be the most dramatic in terms of how fast things change, and ultimately the next seven years will set the stage for the 2030s and beyond.
The rest of the 2020s is going to be dramatically disruptive, then the 2030s is going to see global finance built on bitcoin and lightning become part of the lives of every person on this planet.
