One of the reasons many people still don't invest in bitcoin is lack of knowledge. It is very common for those who are not exposed to bitcoin to think that in order to acquire the asset or currency it is necessary to buy
1 bitcoin, and many do not imagine that it is possible to buy only the bitcoin fraction.
i'm from a third world country and yet the first day i saw bitcoin i had 0% knowledge about bitcoin and yet i just looked at bitcoin at the same time i realized i could gain fractional bitcoin with faucet and i could also buy bitcoin fraction, so I don't see how anyone could not know something as simple as that just by looking at bitcoin
