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.
Cardano team has always been very very involved with their project, they have done that a lot of the time and I believe that they will continue to do that for a long time as well. The problem with it is that all the improvements they did over the years, all the codes they wrote didn't turn out to change anything for them.
Nowadays everyone believes that they are doing something and something special as well, and that is great, many people made a profit, but I am warning people to realize that not much changed for ADA in the past month or so, sure it went up in price but the code is not really that different. Which is why I believe it is definitely going to be a bit weird when people realize that ADA is a highly developed, high tech... nothing. And that will cause the price to plummet just like how XRP did and many others before that.
