I am not saying that everyone must have 1 Bitcoin, but the discussion is that things has changed and it's not as easy as before when 1 personal can just buy 1 to 100s of Bitcoin at a time with small money.
So my advice is, if you can not buy 1 Bitcoin, just buy any fraction that your money can afford, don't fall into the pressure that you have to own 1 Bitcoin. Do what you can, based on your financial capabilities. It's possible to own 1 Bitcoin but not as easy as before when anyone (poor) can easily buy 1 BTC at once.
Almost everyone coming into the crypto space already knows how expensive it can be to own one bitcoin as a very low earner or an average earner or even a pretty good earner. You have to be super rich before you can purchase 1 bitcoin because of how big the price of 1 bitcoin is today. That aside, a lot of people today will still see the price of bitcoin as something cheap for them that they can buy at anytime the quantity of which they want, but it is not as easy as it was in the past when the price was still low.
The value of a bitcoin that was still very low before also didn’t bring the attention of most people to own any that time, as most of them believe it’s going back to zero. Those that took the early decision to buy are enjoying the moments now but even as the price has skyrocketed, people are still there that can afford 1 bitcoin or more but the vast majority of people holding bitcoin cannot buy 1 bitcoin at a buy, some needs to DCA until they achieve that and some cannot get up to that amount and will have to just stop at the quantity which they can afford less than one.
