his $8mil is now only worth $5mil.
I think $ 5 million is still a huge profit, instead of the actual payment. But I would still HODL the coins and see if the profit continues to increase.
I think 50 Cent has enough money to survive a setback in the extent. I would like to know what he was thinking at the moment he discovered his coins.

At this point he should just hold until he needs the money. I bet MC hammer wishes he was holding 700btc at the end of his career when his crew stole all his money.
