5. How can I trade safely?
For the moment we can't offer you any insurance, safeguard or escrow service but we recommend the use of Escrow.com for purchases. If a seller suggests using a different escrow company, please use caution or better drop. You should independently check on any escrow company you would like to use by ensuring it is bonded and licensed. If you are purchasing goods or services and paying through the Western Union, Money Gram or other wire transfer networks, it is your responsibility to verify the reputation and legitimacy of the seller. We suggest you to use an International inspection service too.
Recommended escrow companies are noted below:
Escrow.com (recommended for users from USA)
Escrow Europa (recommended for users from Europe)
Triple Deal (recommended for users from Europe)
iloxx SafeTrade (recommended for users from Germany)
Using the escrow companies above you can protect yourself from fraudulent money transfers. Unfortunately, money transfers can be used for fraudulent purposes by both buyers and sellers; it is therefore advisable that before making a money transfer you be very informed. Make sure you know to whom you are sending money.
