Someone said that Bitcoin is for the rich, but that's not completely true. It might feel like Bitcoin is for the rich due to the media focuses on celebrities and billionaires buying and benefiting from Bitcoin. This creates a perception that Bitcoin is a rich person's asset. Even during network congestion, fees can spike making small transactions very expensive. But let's not forget that Bitcoin is neutral, it can empower the rich or help lift the poor, it actually depends on how communities adopt it. So understand that Bitcoin is for everyone, you can buy tiny fractions, not until you afford a whole Bitcoin.
Bitcoin investment is for everyone and not for the rich alone, in as much as you can buy Bitcoin no matter how lite by little you can afford and start with, as long as you have your discretionary income to start with using your DCA method to accumulate for a long-term of 4-10 years without selling part of your portfolio long the way of accumulation, without having a steady income, but you are sure of seasonal jobs or contracts coming your way.
The process might be very slow to you but regular, consistently, persistently and aggressively purchasing Bitcoin will give you some reasonable amount of Bitcoin in your portfolio at the end of your accumulation target, which will be more profitable to you, than waiting to have a steady monthly income job before purchasing Bitcoin.
The rich buys Bitcoin in large quantity using the lump sum strategy to accumulate because they have the money available to them, that does not mean that Bitcoin is only for them.
In as much as you can figure out some little portion of money from your daily expenses to buy Bitcoin, you are also a Bitcoinner, so don't have the impression that it is only for the rich except you are not willing to have it.
