This is because Bitcoin is the king and father currency in the crypto market, as it gained a considerable investor base 14 years ago and was able to spread and gain its reputation on a large scale, which made bitcoin the most requested currency by people, not like other currencies; also, the widespread adoption of Bitcoin since 2009 by large companies and institutions and prominent businessmen made it more attractive to investors and more credible, in addition to the fact that the Bitcoin blockchain technology is more secure, as it makes Bitcoin the ideal choice for any investor or trader, so it is the leading currency in the market. I do not think that another currency can surpass it.
