This is not something that is new again to the community "Local board" whenever we are carrying out transaction on p2p we should be that mindful on how we release our coin to the buy who always pay.
The problems with people is that they are too lazy to check on what they are doing before hit the pay options, only thing I would have to add here is that we should be trading like 20 percent of total capital you  traded before to reduce on both sides.
