Money now flowing in ADA, suddenly it's already in the top 3 outperforming Binance which has previously achieve that position. However, I think Binance will soon surpass the market cap of ADA as they are a more consistent coin in terms of development and I'm sure they'll continue to chase to be at the top of the altcoin race.
Cardano team is also active with their project. Recently they have updated their network and Cardano will accept smart contracts on their blockchain. This is the reason for ADA to get the price boost. Anyway, ETH and BNB both coins are old. They are popular with their smart contracts platform too. They are not going to loss their popularity. And both of them have the potential to reach at higher price point in the future. But it will take long time to reach that point which has been mentioned by OP.
