Maybe the person already has the bitcoins for a long time and he made a really great profit. Bought them for a double smaller price. So now he wants to try the cake and start something new with the earn money
Well, he's already lossing money. Price when OP created the thread was $235. Right now is 285$ and going up.
If he sold back then he did $10.340.000
If he sold now he could have gotten $12.540.000
He has lost $2.200.000 by being an impatient panic seller, and he has lost the opportunity to have 100 million dollars in the future. If he sold ALL of his Bitcoin he's simply an idiot. You always hold Bitcoin no matter what.
