Even for myself, I don't target quick profits in the investments I have made because I put in an amount that may be small enough for them but not too small for me. Maybe that's the example where I target investment in the long term so a small increase will not see a profit in my portfolio but at some point in the future I think I will see a larger percentage in profit and that may be decades in the future.
It's quite right as you say because if big investors can buy 2 BTC or 5 BTC at once then they will see quite a profit if the BTC increase is above 5%>. Even if we bought $10 in Bitcoin when the price was $15k and now it is $42k then we have seen quite a significant profit in our investment but that is according to the capital we put down. For the long term, it may not be possible to calculate the increase in the short term because the target could be an investment made for in the next 10 years.
People tend to make the mistake of investing little amount of money into buying Bitcoin and lay their hope on getting huge profit within a limited time frame forgetting the higher amount invested the greater your profits.
The DCA has made it very easier for small investors to venture into the market and still make profit, despite the DCA approach being a long term strategy but you don't blame oneself as not being efficient enough to buy in bulk. Of a truth the market is most favorable to whales as a 10% up in price is already giving them good profits per what they invested.
I don't see anything wrong if Bitcoin investors start investing in Bitcoin with a small amount of money and expect big from that investment. If you don't have hope in investing then how can you dream of success even that day. If you don't have a lot of money, you have to be content with what you have and hope for it.
In the field of investment, it is not said anywhere that an investor has to start investing with a huge amount of money rather he can start his investment with minimum amount of money according to everyone's ability. It's not like I started investing with a relatively small amount of money so my investment will stay the same for a long time.
You can increase your investment in Bitcoin and sell it whenever you want, there is no obligation. If an investor thinks that he starts investing with a small amount of money and later sells his investment at will, and when he continues to invest for a long time, his investment will be sufficient and he must expect good things from that substantial investment.
You may believe in the investment principle that you have to invest a lot in the beginning and then you don't increase your investment later.
It is difficult to accumulate a lot of money at once, when you have cash you will need it a lot and you can spend your money when you need it but if you invest in Bitcoin you will not spend that money. So it is always a better decision for an investor to invest in Bitcoin when the amount of money is available rather than accumulating cash over a long period of time.
