Regarding Rydium exchange information, in this forum there is not much to look at, outside the forum there are several reviews about Rydium exchange, as this person said: Raydium Review: Solana’s DeFi Liquidity Mammoth, I don't think the Rydium exchange can be said to be good or bad, it's clear that some considerations and other information are needed, before you use it, for me there are no suspicious signs.
