That could be a lot of money make sure to used it properly. I myself was also too jealous of you luck really comes to a person once so better make used of it. I advice to sell it little by little or if you still belives that the price can go higher then be more patient in waiting
yes, he's one of the lucky ones, and I agree with your advice, that selling a little and not spending it all is a good way. because prices will still continue to rise.
