I think because of it's value which is precious like gold. Digital because bitcoin was created as digital currency which comparable to gold. You know the only thing that’s great about bitcoin that isn’t in gold is that every person in the digital community can have bitcoin even smaller. Many people have bitcoin in their wallet but no gold.
Apart from both having a value which is precious, Bitcoin and Gold also have several other things in common. Like getting it by being mined,
then Bitcoin and Gold are also limited in number. Because Bitcoin is only used in the digital world, therefore many call Bitcoin as digital gold.
In fact, when compared again, both Bitcoin and Gold have several differences, because they are indeed different. There is no need to compare
which is better between Bitcoin and Gold, because both are very worthy of long-term investment. If both are equally good, why should we choose one?.
I even now invest in Gold and Bitcoin.
