I understand that their are scammers everywhere in the internet and also in the physical world. Any business i do with people online is protected under escrow that can't let you be scammed without you confirming the transaction.Many people have been scammed by that reason that if they are sincere then they will meet sincere people in the internet. Scammers are very good in befriending people to show how sincere they are. But in reality everything is just for show to earn the trust of the victim. Be careful with your sincerity to people you do not really know.
