It's not just that it's cheap, open source and global. Fundamentally cryptocurrency is a superior approach to digital money. The first most basic problem that it solves that many payment systems have is the need to _give away your credentials_ in order to transact. This is solved by employing cryptography.

It's similar to when cars started replacing horses in the street. People were so used to seeing little piles of horse sht everywhere that they did not realize what a big deal it would be to finally get rid of it.
