You don't trust exchanges as in you don't want to submit your documents for verification? If it's due to something else, then you could always use Binance P2P and sell your BTC to USDC.

Alternatively, you might be able to find someone to deal with it on AgoraDesk or BISQ directly using your local currency and without having to go through USDC.

To exchange your Bitcoins for USDC with a local trader, you can consider using peer-to-peer (P2P) platforms that connect you with individuals in your area who are interested in buying or selling cryptocurrencies. Here are a few platforms to consider: LocalBitcoins, Paxful, LocalCryptos

LocalBitcoins and Paxful are both entirely centralized and both demand full KYC. LocalCryptos has shutdown.

If OP doesn't trust exchanges, then he isn't going to want to use a fake peer to peer site like LBC or Paxful which will still collect his data and invade his privacy. A better option would be pick a site from https://kycnot.me/?type=exchange such as Bisq or AgoraDesk and use that to find a reputable local trader.

Since you didn't mention your local currency I would suggest you to trade in your local currency through Binance P2P exchange. You can trade directly to your bank account in your local currency via P2P with no problem. Moreover, if Bitcoin is legalized in your country, you can directly contact your trader and trade in your local currency. Your money will be directly in your hands if you contract with your local agent. i think it would better for you to trade your Bitcoin through binance P2P trading process.

Made me think on why you didn't trust exchange but you trust random people online and identity has not been exposed? Reputable exchange is more ideal and you can getaway with scammers for using that option. If worried about fees then you can use some alts which less fee feature.

 The one you ask here is more risky and if I am the one who have that, I will rather choose exchange than people I don't know if I can trust especially dealing with huge funds.

I *think* you missed some sarcasm. LBC and LC have both shut down and Paxful shutdown and was reborn with full KYC

There is always here: https://bitcointalk.org/index.php?board=53.0

The other note is the amount of money involved, a small place in a tiny less wealthy country, is going to involve a different situation then a nice place in the middle of NYC.
That's just the way it is.
Heck, I have a friend who sold some land and a small cabin on a small lake in AZ for less then the cost of his car, and it's only an OK car.

You do not mention your country where we can easily tell you which one is best in that region, Somehow I am suggesting Binance just for your security purposes and the best services provided by Binance. Daily millions of trading occurs on Binance so it's a clear indication that it is safe and secure. You should give your BTC, Ethereum, or BNB, etc. to your local trader, and on Binance P2P he will give you money in your native currency, If you talk to him maybe he will meet you in person to see what are you looking for is best for you.
Besides this, I am also giving some more exchanges where you can also change your BTC into USDT
https://bitquick.com/
https://bisq.com/
https://paxful.com/
These are some other exchanges but I do not personally use them so I advise your Binance P2P if you want to use one of the above three then you need to be very careful and do detailed research for better results.

I'm not really sure where do you live, but if your local currency isn't that popular like USD, EURO, etc, you will not able to find a local trader that willing to trade for 1:1. But for exchange BTC to USDC or USDT, you will get a fair amount. You can also search in google to find instant trade because in my country I can trade BTC to my local fiat without KYC for small amount.

Bisq is good, Paxful isn't no KYC, while Bitquick seems sketchy because I can't read their terms, only a blank white page.

I guess he has a personal reason why he's not trust exchange, most of them are about privacy.

I've heard about various crypto exchanges, but I'm not sure which one offers the best rates and security. Could you please share your experiences and suggest some reliable platforms for exchanging Bitcoins? Also, any tips on minimizing fees and ensuring a smooth exchange process would be greatly appreciated.

Which country are you from ? I believe that we have reputable traders here,that might be in your country, you can contact them and see if they will be interested in doing business with you. Check the service board,you will see market place. If that doesn't work then you should use the options suggested by other poster above. Bisq and Agora desk is better for safety DEx p2p. Cex is easy to use but since you said that you are scared of CEx,DEx will be perfect for you.
