It is my lesson learned that in convincing people about Bitcoin you should not focus in the future. They will not be convinced about it. They are thinking about risk and what will happen to their money. Instead of your predictions which are not a guarantee nor even accurate, focus in the past. Let them see how Bitcoin is transforming into a billion dollar technology from a simple attempt to contribute to a little to change the world. Let them see how the $9,500 Bitcoin started from $0.00000.
