What do you think?
I think they will do. Actually altcoins are doing better since then, although sometimes markets having a bad times which is normal but it will affects the price of alts to drop. If we try to compare the price of top altcoins from previous years then we can say that they are improving throughout the years and they will continue it in upcoming years.
At present the market is in a good position the demand for these is increasing and the prices in the market are increasing you are right that with the rise of bitcoin prices in the coming years altcoin will reach a better position. But in 2021 ethereum and BNB are in a good position in the currency market.
