Of course, all people will be happy because they can make a lot of money. I am sure that at that time, people will sell all of their bitcoin or big amount of bitcoin but I am not sure if the price will stay at a price because if there are so many supplies at the market will make the price down. And if the price is down, no one will know until how deep the price will be down.
Altcoin will not dump to zero, especially for the altcoin, which has a strong community, and even, some altcoin will increase too and maybe, the price will make another highest price. We will not know what will happen if bitcoin reaches that price and what will happen with an altcoin.
