Localbitcoins (which was the best option) removed in-person cash trades two months ago so you're left with either
Mycelium's local trader or
Hodlhodl.
Alternatively, you could use
local.bitcoin.com where you buy BCH in person and try trade it for BTC using an online exchange.
Alternatively, try looking for Facebook groups that consists of people in your city that buys and sells bitcoin. Always make sure to transact in a well secured area like a mall or a bank. If you can, try bringing a few friends with you juuuust to be sure you have buddies around when something bad happens. Remember, money is involved.
