Actually, you are right that there are several other cryptocurrencies that are far more advanced in terms of technology as compared to Bitcoin. But can you cite just one? I bet you do not know a single one. In terms of speed, there are also some others that are much better. In the same way that there are also some other cryptos that offer much more applications. At the end of the day, Bitcoin remains to be the king! Bend a knee!
