That's common mistake of people for thinking about its expensive to buy Bitcoin. The fact that they can buy the smallest unit of it, that determine that they can invest even if they are low budget individual.
Maybe they should eliminate those thinking upon save up then buy a whole Bitcoin. Since if they used the money they have to accumulate right away then do DCA, there's more better chance for them to earn possible huge profit from Bitcoin.
Investing using small amount is fine since what's more important is we start buying and saving for future since there's provably a good chance that we can earn more better rather than getting tempted on short term things. I don't call it as easy since somehow Bitcoin is unpredictable, but if we HODL bitcoin for sure it eliminate the risk and we are fine investing on Bitcoin for long term the same as what they plan to do.
If they can learn more and realize that they can buy Bitcoin by small unit, they will not delay it and will buy Bitcoin by continue especially if they already learn about DCA. So those who only have limit money can still continue buying Bitcoin.
They need to change their mindset and not think that oh Bitcoin is too expensive for me so I can not buy. They should change that mindset because they can allocate enough fund to start investing in Bitcoin. I am sure if they can consistent buying Bitcoin, they will have 1 full of Bitcoin even more by using DCA. That will only a matter of time for them and when they can achieve that, they will be happy and never though that they are succeed doing that.
Investing in small amount is not be a problem as Bitcoin understand that many people don't have large money to start. People have the best investment now so they can start before it's too late. We are just hodl Bitcoin for some years like we saving our money in the bank but we control this bank by ourselves and not let other party manage it. It is fully control by us.
