You can open a thread already.
My advice: Never trade Crypto with reversible payment methods, except at a company-website with reputation or a trader here that has a long history of trust.
Even then a risk remains.
You can also trade here, but have to check the trust and history and old posts of the trading partner. At least 80% of offers here at marketplace are scams.
At almost all Peer2Peer platforms like localbitcoins and paxful its same story with paypal, skrill, neteller and similar options.
Also Banktransfers are dangerous.
Trade local with cash, use an ATM, use MG and WU or use commercial resellers or one of the big exchanges.
Or trade with someone you know personally.
