but people often forget about one small non-kyc centralized exchange Tradeogre, that exist for a long time.
They support bitcoin, eth, monero, USDT, USDC and other coins, so they should be fine for smaller amounts.
Which one you have in mind? I used to use one but it's been long time I am not using it. I can not remember the name of it too. The site was very simple. You do not need anything else except they give you a deposit address, you give them an address to receive your coins. You send coins and they give it back. It was KYC free too.
