This is an interesting list of course satoshi nakamoto would be numero uno.

But the government of bulgaria has this much bitcoin?

How did they accumulate so much
cheap electricity & mining since 2009 maybe and do they want to be the richest crypto country in the world?

Jeff bezoz and other top richest man won't let this happen i think haha
Also it's impossible to reach even 100k if the crypto itself is not mainstream in this world yet.
