The price of monero at that time was around 50 cents and that means he has spent 92k USD to buy monero. If he was from the rich family and it will be easy money for him to brough a lot of monero at that time. Im not feeling surprised to see he was able to bought a lot of monero at that time.
His investment has become multi million dollars. He's so lucky.
How about mining them? i think its cheaper to get them by mining at that time. However the way he get the coins, his decision so lucky.
Exactly my thought. He must have mined then as it was very easy to mine XMR in 2015 than today. But how can a user of XMR be traced? How can he be known of owning such a big amount of money when this coin can easily hide his money for ages?
