10 or 20 years from now, when bitcoin's market cap equals or surpasses the gold's market cap, we will look back and think how lucky the people who bought bitcoin when it was under $1,000,000.
The time will also come where we will not talk about buying bitcoin, but instead buying satoshis.
We will always count ourselves lucky for buying Bitcoin when it is below $100k. I can't tell whether there will be many of us hodling Bitcoin at the moment, that will hodl Bitcoin till when it gets to $1 million before selling. We might all sell at a price far below $1 million because we can't tell how long it is for Bitcoin to reach $1 million. It might be more than 10 years. Mind you, the market is unpredictable, not every one of us will have the patience to wait till when Bitcoin steps $1 million as a price before selling.
