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.
If Bitcoin continues its growth in value and price, and if you can accumulate bitcoin for your long term investment in sustainable way, I am quite sure that by investing and holding, you will be able to get good profit.
It sounds easy but to succeed, there are many things need to be handled well enough. You can not bet all your money in bitcoin in 2025 without any money reserved for other things you have to spend in near future, so I am sure you won't be able to hold your bitcoin till it hits or surpasses $1M in price. Your saying sounds like from market makers who don't want newbies to sell, just buy buy buy in bull market hence stuck in bear market.
Good or bad, profit or loss, it depends on your entry and how long you will be able to hold your bitcoin.
