About Binance

They justifies delisting because of smart-contract vulnerabilities and lack of development (Monero is under high development and dont have smart contracts because it’s made to be digital cash 🤨)
Increasingly halting withdrawals even after delisting ( monitoring chart )
Users are complaining about a 3 XMR limit, we talk about 300$ that’s a very very small amount that even your hood friend can refund you 🤨.
People can be rewarded in USDT by taking risk to hold paper XMR if they can’t withdraw them so hold if you can’t withdraw to create a debt ( announce ).

ChangeNOW, FixedFloat and SideShift

Exchanges like Binance, KuCoin (as examples) haves swap features used by all theses “non-custodial” exchanges, they just get referral on swaps you make.
Technically by using then you’re just feeding their reserves so again opt for Bisq.
Since Binance fully stopped monero spot trading, sideshift and FixedFloat stopped monero swaps.

About Huobi & Poloniex.

Both haves closed withdrawals, with proven price anomalies. Compare PLX + HTX versus TradeOgre or Bisq
Huobi is very likely insolvent due to a hack and PLX were bought by Justin Sun (Huobi owner)

What can we conclude of this ?

Most of exchanges giving on monero:

Leverage
Lending / Borrowing

Struggle in reality to cover their reserves. People should also avoid as much they can KYC platforms, where they can get restricted on their trading/arbitrage activity like we seen on CoinEX. KYC and AML leads to frozen funds so money losses.

About CoinGecko & CoinMarketCap

No one knows on what their “trust score” of an exchange is based.
It changes constantly and they don’t list all exchanges (BasicSwapDEX, IncognitoChain, SevenSeas ect…)
