It is really tragic for him
He must have been shocked by 2017
But who knew BTC would visit the moon
Also, you must bear in mind that he bought the BTC.
If you watched the video he didn't regret spending 1000 BTC on a Prius. He did invest because of the loan and all of the BTC used to buy the car came from his profits.
Although it paid off for him, borrowing money to invest in bitcoin (or anything for that matter) is generally a terrible idea.
I agree it was very risky on his part. He's lucky Bitcoin's price doubled when he made that investment decision. If someone did the same decision today or last year they would be at a huge loss.
