Same goes for gold. Nowadays you can buy digital gold or digital Silver as an investment. Similar to Bitcoin, you can buy digital gold or silver in small units. Gold has been used since centuries as a capital protection asset so people have options available in the Market.
You seem to not understand bitcoin and/or not understand gold/silver.
Bitcoin is digitally native, and gold/silver have physical forms. If you digitize either gold/silver, they still have physical representations that need to be referenced... which can lead to complications. No?
I will grant you that there are attempts to create paper versions of bitcoin, and there are even real people who are contractually agreeing to waiving their right to actually possess the bitcoin, yet bitcoin still remains way easier to physically possess (referring to its private keys) as compared with physical gold/silver. The difference in their nature means that there are going to be challenges in terms of third parties not having the bitcoin they claim to have, and the world still needs to find out how these differences play out.
That's right, don't get caught up in the idea of digitizing gold, and don't get caught up in the idea of materializing Bitcoin. Both should remain in their original domains, and if there are attempts to digitize gold and put Bitcoin in paper form like fiat currency, the value will not be the same. Its essence has been manipulated, and we must learn that the current medium of exchange is no longer backed by 100% gold.
They use third parties and officially state that the physical gold exists. Yeah, that's true, but the worst-case scenario will come at an unexpected time. Even if Bitcoin is made physical, third parties cannot guarantee that storing it for too long will be safe forever.
Which brings us back tyo the actual factual situation that individuals can learn how to store, take custody, secure, transfer and transact in bitcoin, and it is much more cumbersome to try to do the same with gold or silver.. Especially large quantities, and even something like $10k worth might be very cumbersome to move, especially if we might be crossing over borders.
Surely there are a decent number of folks who are purposefully encumbering their bitcoin so that they are not able to take custody of it, yet it may well be the case that some people are going to learn that either holding bitcoin yourself and/or not encumbering your ability to hold your bitcoin is largely what makes bitcoin valuable.
