It is very difficult to predict which coins will rocket, because the crypto trading character is full of speculators where they do not want to hold inconclusive coins on the market. They tend to choose coins that are already established because they believe prices will definitely rise, along with the increase in the price of bitcoin.
Coin BNB is predicted to become a rocket when it is launched because it is affiliated with Binance, the crypto trading site. It turned out that the prediction missed and today only has a price of USD 32. Of course it is still far below the ETH which reaches USD 270, especially when compared with the price of bitcoin that already exists at USD 9120.
