His name was Tony Vaughn and he was from Kentucky. He was paid his salary in bitcoin in 2013 , at time when very few even heard about bitcoin. If he would have not sold those bitcoins that he got as salary, he would might have been a billionaire by now. Because bitcoin price at that time was just $1000 a piece , so his wealth would have been about 30 times at current prices.
I am really sure, He probably didn't spare his salary at that time because he had to fulfill his life needs such as bills, food, etc, and maybe if he really saved his BTC, that is possible a only few satoshis left on his wallet. because BTC price movements would make people tempted to sell it. Maybe we can equalize Tony Vaughn with signature participant who got payment with btc, because there are many necessities for life, they might sell some, and set aside some. But I am really sure, some of them will sell everything if BTC price back to ATH or more than the previous price. because there are still many people still compare BTC with fiat.
