Cardano has a chance to pass Ethereum. However, if we look at the current condition, it won't happen very soon. Or maybe the chance to pass Ethereum is rather small if no bad things are happening in Ethereum. Everybody knows that Ethereum is the king of altcoins, it is leading all altcoins. So, to pass this coin isn't something easy to happen. There should be a big improvement in Cardano to compete with Ethereum.
