Gold in general is no better. The value of gold is nothing more than a result of a global consensus - at the moment everyone agrees to consider gold a measure of value, simply because this measure is in some form or another necessary. If we assume a utopian situation, that tomorrow everyone agrees that gold is not such a measure, then it will be good only for the production of quality wires and trinkets.
The btc is gaining momentum for exactly the same reason - the global consensus towards the btc is constantly being strengthened. In this case, unlike gold, the cue-ball is not only a measure of value, but also a settlement system, and gold is not a competitor for this parameter.
For me gold cannot be replaced by bitcoin. In the first place golds are mine from hard form rocks or inside the cave. While bitcoins are mined from virtual technology. Golds are verry precious, it is mold by hundred years while bitcoin is said to be a bubble.But when it cxomes to value, maybe bitcoin can rise as much as gold.
Why does Bitcoin called a bubble? Is by its value? You have to know the bubble price and the real price for the asset are set by the community. The Bitcoin and Gold price are also set by its community. Until the value dropped below much values in the future, these assets can be the bubble.
