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.
You see one thing, it's that chase after one Bitcoin that drives the market, and as long as it's healthy for the marke, I don't see anything wrong with it. If you can afford one Bitcoin as whole, go for it because if I'm opportune for the same, I will buy more than one Bitcoin, the institutional investors are taking everything and a time will come when you will hardly see one person that hold one Bitcoin, imagine a Bitcoin worth a million dollars will be very scarce.
However, there is no reason why you should make yourself uncomfortable because you don't have the means to buy one Bitcoin, our finance pocket is different, and even our hands are not equal. If it's half a Bitcoin that you can buy, go for it and if it's quarter you can buy, go for it. There is no need to buy a whole Bitcoin when you don't have the means. Beside, you can do DCA in the future as you have more funds in your way, there is no law that says you should never buy more Bitcoin.
