Sometimes it takes time and people on the circle of your trust to get that green trust though. You can check this general board of
Marketplace, it's where you can gain this trust if you're into p2p trades and escrow but it isn't limited in here because you can gain trust on other boards as well, for example, your local board if you want to start your service/s there.
Well I understand your point, but those
circle were leave positive trust isn't correct if it's because the user is nice to you and not from risking a money. Also you're like teaching him how to farm positive trust and make him looks trust-able, while it doesn't good.
Circle isn't the right word I guess but more like those who he/get traded with in the past and besides users can check feedback on those trust too for legitimacy, my bad saying it as circle. It's not that I'm teaching him like that when in fact I don't have the capability of those on myself in my trust profile to justify your opinion. I'm just saying that this is where it will leads to in the future if somehow OP is that trustable with his/her service and not just being nice.
