This is naturally good news, but it should be mentioned that this dominance is achieved by selling many altcoins, which in turn is a bad sign, because people do not believe in them, and therefore in cryptocurrencies....
This is a false dichotomy. I completely believe in Bitcoin's ability to change the global monetary system, and I also completely believe that 99.9% of altcoins are complete trash. People are starting to wake up to the fact that most altcoins are just empty promises, with no working product and no future.
