You can easily convert btc without verification but you will have limits or the way you receive money will require verification like paypal, neteller or etc but with low money that's ok. What about bitcoin ATM's?
Also you can trade with people here. Use paxful - they don't require verification.
But I think the best way could be localbitcoins or any other small exchangers.
I've never used a bitcoin ATM, but have heard/read that anyone buying from bitcoin ATM must provide ID.
....
Decentralized exchanges are also an option, but I don't know which ones are the best to use.
....
But don't most decentralized exchanges deal only in crypto/tokens? i know waves dex deals in fiat, but in order to deposit/withdraw via fiat gateway one should give their IDs.
Edit.
