Where can I buy/sell BTC and XMR in person for cash like localbitcoins.com back in the day, where you setup the meeting, meet and do the transaction in person for cash. A lot of these websites came and went, what are the current ones where I can find a counterparty to trade with in person?
Is that a large amount?
Meeting in person is very risky; it puts your life in danger when dealing with people directly.
P2P would be a great help at this point; it's safe and involves no physical contact, as mentioned above.
However, keep in mind that trading or holding XMR is not illegal in your country, but exchanges may avoid listing it to comply with regulations if you choose CEXs and restrict US users due to compliance issues.
In my opinion, I suggest buying BTC/ETH and converting XMR on the DEX.
