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
Reading this kind of thread really inspired like me who just starting bitcoin a few months before. I hope one day i can also get my luck on this and waiting for my first income from bitcoin. Patience is one of the key factors for this.
