I will suggest just 1 thing. That is we will allow only to give 1 feedback each account not like multiple feedback.
Taking feedback from same person multiply times rating increase so much and don't give true sense.
So better if it will only give us chance to feedback once.We will able to update/modify that if we want but not multiply the feedback many times.
Then you're weighting multiple successful trades the same as one.
Yes, we can update BTC section if we want and we can update feedback by saying did multiples trades. But multiple feedback give more value suddenly, that's why it's not look good on trust system.
I do lot's of trade. And even I gave once feedback even they always again ask feedback for every trade.
I don't think if we already gave feedback it will be necessary. One feedback each account will fulfill the requirement of true Trust system.
