Your topic has nothing with the main text, but I'm ready to reply both.
Bitcoin was called as digital gold long time ago, and the main reason of that was that bitcoin is also can be mined just like gold. This collation is used to explain bitcoin to newbies often, cause of this way it is easier to understand the whole idea of crypto.
that may be it but i believe so many these days are calling bitcoin "gold" because they want to imply that bitcoin is not a currency and it is only a store of value. although you may never know why some people say it, maybe some call it gold simply because they want to imply it is too valuable!
and they may be true, bitcoin is not functioning as a currency these days with these high fees and huge backlog. but what they don't realize is that i am afraid not being a currency can kill bitcoin.
