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.
2013, Bitcoin price started the year at $13, and only reach that $1000 at the end of the year 2013, and it faced a lot of corrections, by December of 2013, Bitcoin closed the year at $754, so OP, when did this person get paid with Bitcoin? Because that's what will determine what his value would have been if he held till today, no link to this story? It's lacking more information.
I think it's a lot of money if he get paid when Bitcoin is at $13 but let's pretend that he got paid at the end of the year @ $1000 per Bitcoin, what is the salary of this man you are talking about?
A $100 invested in Bitcoin at the beginning of 2013 would get you roughly 7.5 BTC and today that's $277500, that's not even close to a million dollar, this is why it's important to know how much was paid to the man in Bitcoin. If we invested $100 on Bitcoin when it was at $1000 the value will be much less today, so there is no way this man would have been a billionaire, not even a millionaire.
Still, we don't have the information on how much he really earned so we really can't say, also I doubt that he would have hold the Bitcoin to date, not everyone can do this while the need of money is telling on them.
