For many years I have seen that bitcoin will always be the leading currency. There are thousands of other coins that entered the market but only bitcoin withstand for years and even moon wit the all time high price. No one knows and can predict the great future of Bitcoin.
Indeed. Bitcoin is gaining it's popularity since it was created, that is why more people are buying bitcoin than other cryptocurrencies that makes it the leading currency. Also, most coins in the market don't have any good value, that is why they are putting most of their coins in Bitcoin and other top altcoins like ETH, BNB, BCH, XRP, LTC and etc.
