I sent to 32d95R8SRKemnMugBF1kRKBbofMDnJSUst (when paying through sell.app) this wallet seller in support ChangeNow (web3.0 exchanger) I confirmed that the money I exchanged to bc1qc5ctv042wag2wag6pdpxaak2h6r9wp0fw3h9zh57z
These exchanges
And indeed, the crediting time is the same as what I sent from binance
