Wow... Imagine having more than 100K amount of bitcoin.
If I had this much I would go somewhere and enjoy for the rest of my life.
because we all know what will happen in the bitcoin halving. Even in my dreams I can't imagine it it
I remember that there's a meme about the quantity of bitcoin that a person holds.
If it's above a thousands, you are a whale and when we have less than 0.1
BTC, we were called a shrimp.
I think you already have the answer for your question and it's not a single person that owns the most but it's a company, an exchange.
