It all depends on what you Buy OSRS Gold from. I generally avoid huge websites that offer unlimited stock in a variety of games (usually Chinese traders too). If you browse an online marketplace such as RSorder, there are a lot of players who are selling their Gold. In addition, you will get the most competitive price however, the site's transactions system which is based on Escrow assures you that you will get the price you pay. Additionally dealing Old School RuneScape Gold with other participants (even in the case of RMT) will be the most secure method!!
