لا يمكنني اقتراح اي موقع بسبب محدودية الخيارات اونلاين، و لانها ليست مؤكدة الموثوقية فلا نجد تقييمات قيمة. الاقتراح الوحيد الموثوق ه

I cannot suggest any online platform because options are very limited, and not trustworth confirmed as we can't find valuable reviews. The only reliable suggestion is the "Digital Goods" sub-board here in bitcointalk forum, where you can find veteran reputed members running their trading business, and others offering Escrow services + forum tools like the trust system and report to mods feature.
