As we know that Monero's (XMR) advantage lies in its function as a full anonymous cryptocurrency (privacy), unlike BitCoin or some other crypto which we can not call Full anonymous because if I know the wallet of your BitCoin address
There is way more to Monero than fungibility, privacy and anonymity.
There is also the reality that at the protocol level Monero can scale while Bitcoin cannot. The competitiveness of Monero's ability to scale at the protocol level, has been clouded by the very large Monero tx size when compared to Bitcoin. This difference in tx size of course has noting to do with Bitcoin's inherent inability to scale at the protocol level, since no amount of technological improvement such as moving from punched cards and telegraph lines to smartphones and fiber optics will address Bitcoin's scaling problems. Still bulletproofs could easily, by decreasing tx size in Monero by ~80%, remove this negative cloud of relative tx size and expose Monero's fundamental scaling advantage over Bitcoin to the market. If this happens I would not be surprised if we saw a significant price increase of Monero with respect to Bitcoin even in the range of ~10x. A scenario of say Bitcoin at 8,000 USD and Monero at say 2000 USD is actually not that unreasonable in a neutral to bull market or that matter say Bitcoin at 800 USD and Monero at 200 USD in a neutral to bear market scenario.
Edit 1: That above scenario is very consistent with the sharp drop in Bitcoin dominance we have seen over the last 3 years.
Edit 2: When the Diner's club was launched in 1950, they charged merchants a 7% fee to process the transactions. Today a Canadian paying for gas the United States with a Canadian credit card ends up paying more: A total of ~7.5% consisting of a ~3,.5% merchant fee that is passed on to the customer and a hidden but very real fee of ~4% over mid market rate charged by the bank on the CAD / USD currency exchange. So while the actual cost of processing this transaction has easily fallen during the last 68 years by a factor of 10
12 or more, the end user cost had actually gone up. Why? Because the credit card industry business models (equivalent to protocol in crypto currency) are still based upon the technology of the 1940's.
