Nope, there are only few good coins, while the rest which is 99% are actually bad coins.
Top exchanges only list a coin that has a big traffic, popular, has trading volume, and not privacy oriented. Monero is a good coin, but since it's a privacy coin, many centralized exchange delisted this coin.
A high liquidity and popular coin isn't always a good coin, take a look with FTX token, UST, LUNA etc.
The average coin is good in my opinion but it only lasts for a while there are some networks formed that have high potential but they are slow to adapt so the technology lags behind other competitors so the coin is a coin that has no value today, regarding FTX and Luna, in my opinion, is good if you look at the coins, but the development and management were not good, causing the destruction of the coin project itself, as well as the coins on the exchange, but it's true that exchanges only take advantage of the volume of traffic to make a profit, good coins are subjective it's up to one to see the value in the project itself, twbut no coin is as good and strong as bitcoin.
