I also think that Binance is the best platform, but it is really subjective where the answer depends on the user. There are some unique features that Binance have while the other exchanges doesn't have. The volume is also matter because it indicates the number of coins that are being traded daily in the market. I do not like some of the exchanges because of the low volume and also the slow support that can considered as inconvenience and uncomfortable.
Not each of the exchange can be trusted. Most of the exchanges who never have any greater volume end up by scamming their users by creating fake pumps and dumps as due to the lower volume, manipulating those coins gets much easier.
Perhaps these new exchanges might keep some more attractive features than binance which might include Lending, Staking, etc but it depends on us whether we want to trust that exchange or pass on the trades. We always have reputable exchanges so why would we go for exchanges which are newly created and also do not have any proof of existence.
I completely agree with you, the exchange market has long been captured by top exchanges. Attracting new people to the new exchange is now an extremely difficult task.
Remember what happened to the Coinsbit exchange which is now considered a scam exchange on the forum.
Coinsbit conducted an extensive AirDrop with the promise that everyone will receive $ 200; as a result, many people created multi-accounts and joined the exchange,
which created an artificial excitement around her.
Subsequently, everything turned out against the exchange, people did not receive anything, and the exchange was accused of scam.
