To determine whether BTC is better than USD and gold, we must know in what case. If it is on the case of investment for the long term, I think BTC sometimes holds a very significant chance to be the best to get bigger profits. however for the volatility, BTC is very volatile and the gold or USD is more powerful and stable, mostly the two are increasing.

Lol, the dollar has the backing of federal reserves, all the assets of the government (which infact is elected by people) and global trades carried out in USD.
Also, the relative value of USD and all other currencies is decided by World Bank using the PPP for a basket of goods and also the health of the nation's economy, whereas the BTC is just plain and simple, expectations.

I am not saying it will always be this way but as of the current scenario, the price of BTC/Crypto is mostly derived from speculators traders.

Bitcoin, Gold, and USD are indeed different from each other, but all three are sought by people because all three can benefit us.  If according to its function, Bitcoin and USD might be the same and Gold is the most Different.  But even though all three of them are looking for people because they can provide benefits, Bitcoin is the best in terms of the highest potential.  The price of Bitcoin can soar very quickly, and it has never been owned by Gold and USD.  In this case people say, Bitcoin is better than Gold and USD.

Bitcoin is only better than gold if the power grid remains up. If you want the grid to stay, join with a few friends, and get a Kubota 10kw generator for your neighborhood. Save money by getting off the power company, which will be controlled to crash, just to bring the grid and Bitcoin down.
