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?
For now, I still see bitcoin to dominate the cryptocurrency market in the next 5 years as altcoins are still considered great followers of bitcoin. But I know for sure that there might be some new projects that will be more known and profitable within that 5 years of time frame, but the problem is how long they will be profitable and reliable in the market. Unlike bitcoin itself, even if it’s price increase is very slow for now, but we all know that it will always be reliable and more secured to give us future profits than losses. That’s why a lot of us still chose to invest in bitcoin, and still expecting that bitcoin will always lead the market 5-10 years from now.
