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
Me too, it is possible that bitcoin can make someone millionaire, but remember that it is not just like walking down the street that in one night you can obtain . If someone became millionaire of course he tried everything , maybe he invested so much here, and maybe he already have enough bitcoin for someone to becamemillionaire, and bitcoin raise it value, so ccongratulations!.
