On
https://phenixst.com you can get a completely secure escrow service for BTC, LTC, and PXC.
Escrow is when a third party, in this case phenixST, handles the funds of both p2p traders. You fund your transaction, and send the buyer the transaction ID. The buyer will then make their own account, search that specific TXID, and fund it themselves. This way both parties cannot scam each other.
Simply make a new account, new transaction, fund it with LTC, PXC, or BTC, and sell it for LTC, BTC, or PXC.
