When has this list been made? Because a few weeks ago when Ripple had peaked the news came out that Ripple's boss had become briefly more rich than Bill Gates - so I guess he would have been quite on top of this list. But things change very fast in cryptos...
Wow, I have no idea how it becomes possible. But, on the other hand, everybody who is doing something different, have chance to become rich. In future we will see new and new names in this list, and I won't surprise.
