Most of these tips are precautions. Just try to buy and sell from someone who has a good reputation and wants to maintain it.
The only issue I have with following these tips is it encourages people to not go to new users...but for good reason. I just wish there were more people in my area selling/buying bitcoin
If you not to go or trade in new users how they get a chance to make their nane became famous? Or the reputation that they will get?I know the risk you trade in new users but give them a chance to prove that they are not scammer and to prove that they are trtrustworthy
