You can now trade bitcoin and other crypto with other local traders on Binance, and you will meet at a particular place that both of you talked about.
This is just not different from KYC if you trade with a bad person. Avoid such physical trading.
This is not a good idea at all; this one is the worst one, and someone can easily be attacked. This can also lead to kidnapping, similar to the two cases you listed above; for me to go for this option, I would rather accept KYC and trade directly from the exchange because this one will never lead to a good result because we don't know each other, and no one is providing external security.
I think these are signs for us to keep avoiding centralizing exchanges because of trust issues. It cannot be possible for me to have money and still have no rest of mind because of where I saved or kept my money. I will be using exchanges for just buying crypto and selling them to fiat, but keeping my bitcoin will always be done in my Electrum wallet.
