Whats in it for them I'm wondering but also I'd like to know the answer if it exists
these developers are making money when people use their product which isn't a bad thing but i still don't like the idea of it, i prefer peer to peer trades if i am to use a "decentralize" exchange.
Why does it seem to you that some exchanges are not fully decentralized? Is there some evidence to back your claim, if so I am sure everyone would be willing to dig into it.
in a list i saw there was a couple of them that didn't look decentralized at all because they were using a server that could also log everything. there is also binance DEX that exists in most list and is fully centralized with all the sign up requirements and the restrictions it has!
If you want to simplest bitcoin<>altcoin change then a CEX is better in terms of both liquidity and ease but bad in terms of trading fees.
if i wanted to use CEX i wouldn't have started this topic!
No trading fee would mean no earning for the exchange. They need to reap some profit otherwise they are going to go bankrupt.
a real decentralized, peer to peer exchange has no cost for them to go bankrupt. it is fully peer to peer, it means you are using your own computer to connect to another person's computer and make a swap.
it is like saying "bitcoin core devs have to take a fee from each transaction we send using bitcoin core or they will go bankrupt"
