I appreciate everyone in the bitcoin community has either been burned or seen people get burned, but there is no reason to be automatically hostile. As far as I can see these seem like friendly people and have offered anyone in the area the chance to pop by. Someone take them up on it and pop down.

Good luck Cointerra.
