idk if i totally agree that small money is useless because it still beats having your cash rot in a bank account at two percent interest, sure you might not get a lambo from a twenty dollar weekly dca but you will still be way ahead of everyone else in ten years, it is all about perspective and what you consider rich
I can't help but agree with this, because $20 a week might look small in the present, but if someone keeps doing that for years, it will become a pretty good sum, and then if the price of Bitcoin keeps appreciating over time, the person will have good enough savings in the future, way better than keeping the money in the bank and allowing inflation to make it lose purchasing power over time. It's never a good idea to save all your money in fiat, just keep some of it for emergencies, but always try to buy assets that won't make your money lose value or purchasing power, if you don't go with Bitcoin, go with Gold.
I actually believe that those who are capable enough to DCA into Bitcoin, regardless of the amount being used, are lucky and blessed, because not everyone gets to spare some funds to be invested in Bitcoin every week or even every month, and those who can do it shouldn't leave the opportunity, even if it's only $10, even that will make a difference, because as they say, something is better than nothing, so if you don't do it thinking the amount is too small, you will regret it in the future, for sure.
