if the price of bitcoin increased to $ 1M, I guess all the bitcoiners dreams will come true. home, car, motorcycle, business, everything will go smoothly, and perhaps the most bitcoin holders only live to enjoy his life alone. Imagine if you have 1000 BTC in your wallet, it could make a leisurely life
There would definitely be a lot of people selling once Bitcoin hits $1m, and that would more than likely be a large majority of the community that's here right now. They would be able to live in relative comfort, assuming they don't spend too much, and would more than likely be able to retire a few years sooner than their peers, if they choose to do so.
1000 BTC would make you a billionaire, so you might as well get ready to pay your taxes.
