This is how crypto market works and you will find many coins replacing each other on CMC as per market cap and prices like doge has entered the top 10 list and this bull run many coins came with insane pumps but this doesn't imply they have growth opportunities and sound project and Shiba Inu is soon going to face similar things.Low fees should be a priority but the coin should also be worthy to be traded.

You're right, of course, just because it was like that in 2017 doesn't mean that it will be the same for "fun coins" (like Shiba and Doge are, in my opinion) in 2021.
However, I am personally convinced that especially projects that solve actual "real-world problems" have a very high potential to survive even a bear market. Hype coins tend not to have that, and when the hype breaks down, so does the price.
That is the fundamental approach to crypto basically. If you believe that a coin has a potential to provide any utility and actually could be used for something decent, then you are going to end up with a proper return, if you are investing just because you see a "fun" thing going around and the community is supporting it, then you are going to lose a lot of money. That is how people approach to things, there is not much you could do because you are right and others are usually wrong. Check the marketcap of shiba and doge now, and check it 3 years later, you will see that it is ranked a lot lower, but check things like btc, eth, ada, sol, bnb and so forth and you will see them go up.
