the feedback system needs to change,
We all agree. To be honest right now it's not a feedback system but a system where you leave your comment or make conversation. It's same as we are sharing our opinions to each others in the forum. The difference is in BestChange when it is positive comment it is showing positive review (green I assume) but when this is a complain or negative comment it is showing as only comment, not considering it a review anymore. And finally where they are showing their overall score they are only counting the positive feedback to mislead the visitors know anything that is happening in the negative side.
How are we going to confirm the user who lost his btc did not find the website x,y,z from search engine or any other ad?
They found the exchange from a random source, exchanged and it went wrong. Then the guy found BestChange advertising the exchange and he wanted to have their help to resolve the case. But when it did not then they are in the forum seeking our help. How are we going to know all of it?
I don't think that matters.
I was using it for analogy only that this could happen too.
