Now I can't buy even 0.1 bitcoins for $100, but in the past someone bought a few hundred bitcoins for $100.
Of course you cant buy 0.1 Bitcoin with 100 dollars today but you can buy 0.0025 Bitcoins with 100 dollars. I too came to know about Bitcoin in 2019/20 but that doesn't mean I am late to buy Bitcoin now. I created a table
today that shows how effective it is to accumulate Bitcoin in DCA manner. Gathering Bitcoin is effective only if you are planning for long term investment. Do some calculations about Bitcoin DCA
here and you will be amazed to see how effective still Bitcoin accumulation will be if done in right manner.
In my opinion, those who think it's too late to invest in bitcoin are those who intend to get rich quickly with bitcoin, they want to become rich with little capital like early investors did it. So I think introducing the DCA method to these people will not be effective. I mean, first they need to better understand bitcoin, the potential of bitcoin and the benefits of bitcoin for us...Once they still do not know the real benefits of bitcoin, telling them to invest or accumulate bitcoin will not be effective for them.
OP or people who are still thinking of getting rich quick from bitcoin, what they need first is basic knowledge about bitcoin, because according to what OP is saying, I believe he doesn't even have the knowledge yet about bitcoin let alone DCA.
