I have suggestion for ya all. Why not keep calm and let this thread rest in peace for a week. Let's come back on Wednesday next week and start this brainstorming session once again. Until then, there is no point discussing same point again and again.
Bestchange's profile already have 2 negative trusts which is enough to alert anyone joining the campaign for now. Other than that no one cares whether anyone posting in this thread support/oppose giving red trust as warning or consider Bestchange trustworthy or not.
Maybe OP not accepted in Bestchange signature campaign where become most higher payment from other signature weekly by bitcoin, why not give one week before making discussion about scam or not with bestchange site, the OP look beginner in online world because he don't know about Bestchange, I have participated in this website last three years ago where giving reward for new participants.
