Gold only has value because people want it.
People claim that but it's not really true, it's because the class of metals known as noble metals are some of the few substances that fulfill the checklist of requirements needed of money like durability, portability, scarcity, fungibility, divisibility, etc.
Or to put it differently, gold does not react with oxygen or water, and the planet is covered in both, so it's one of the keys to the durability checkmark. Silver also does not react with oxygen or water, but it will tarnish from random hydrogen sulfide it runs into in the air. This means for human purposes, gold is more inert and money is supposed to be as boring and unchanging as possible. However, the overall durability and inertness of gold, silver, and platinum is mostly negligible when compared to one another, and especially against all other competing non-noble metal substances.
Gold has the benefit of being more inert for human purposes in this ecosystem, but it's also softer than silver, so would actually be less durable in that regard, giving pros and cons to both with gold not actually being a clear all-around winner. The purpose of the durability is to transfer generational wealth from one person to another, acting as an actual decentralized blockchain without an exposed power vacuum to be taken over and turned into a permissioned ledger monopoly, unlike bitcoin.
Yes, it's true, metals are the real blockchain and bitcoin is a poor Rube Goldberg imitation with huge overhead, built-in middlemen, and non-removal of counter party risk. As can be seen by comparing the aging of Roman coins, both metals fulfill the role of "durable" and inert enough with the various differences being mostly a wash as talked about above. These pictures are of a blockchain that's billions of years old. How old is your shitty blockchain?
Why you said that gold and silver are a blockchain? They clearly are not.
Gold and silver are a pretty different thing than blockchain technology, I really can't understand how you can consider them as some kind of altcoin. They are a way to store value, not a cryptocurrency!
Anyway, I like the gold one! How many btc for that?
