Ethereum (ETH), Ripple (XRP), Litecoin (LTC), Tether (USDT), bitcoin cash (BCH) These coins are much more popular. The amount of investment in these is constantly increasing. But the best on the market is Bitcoin. In terms of popularity, Bitcoin is next to the above coins. However, the price of ripple is much lower. Once upon a time there was a lot more growth. But the competition for some coins has outpaced Ripple popularity. So I think a lot of coins will come to compete in the market. However, the coins that are currently popular will remain popular.
