I think bitcoin will lead the currency market because it was created as a way for people to send money over the internet. There are many advantages of bitcoin like Direct Transfer, Greater Liquidity, Security and so on. Bitcoin's maximum supply is limited to 21 million coins. Cryptocurrency gains value when demand rises higher than supply. for that i think bitcoin will lead the currency market in near 5 years. Which currency you think will lead?
Seeing what bitcoin has obtained so far since its inception, it is clear that bitcoin will continue to dominate the Cryptocurrency market and so on because bitcoin is the only coin that we can trust for the long term besides bitcoin we can say that its presence is only as a complement to bitcoin on the market, even though at this time there are already thousands of altcoins and some of them have been developed more sophisticated than bitcoin, this does not make investors interested in adopting them other than bitcoin.
