IF a buyer had 100B+ succesfull buy/sell trades I would deem them trustworthy.
I base trust more on other factors besides vouches. For example people like me don't use the market much, but that doesn't mean we're not trustworthy.
I look at a variety of things including how active they are on sythe, what is their personality like, have I talked to them on the IRC, and I do look at their vouches. However someone like Sillymonkey, who isn't necessarily an active market person, I would trust with more than I care to admit, lol. You just have to look at everything overall, and that is how you will get the best idea of whether or not someone can be deemed trustworthy.
I do not use the market, I use the community side more. I also tend to go on what is their personality like also and if they are a nice person. I only have 1 vouch so I wouldn't see people trusting me.
Id say 200+ vouches and 50b+ traded
For most people, I look at who's vouched them and what they said about them, the amount isn't that important. However, someone who I'd consider to be clearly "trustworthy" (to varying degrees) would have hundreds of dollars worth of trades or at least 75 vouches.
I would believe at least 20 vouches and 100m rsgp traded.
1b would be enough
I don't really care.. I can get everything I need from people I already trust.
I would look at vouches more/how well I've known the person than amount traded.
The amount traded should be around 20-50B+. I would also look at the vouches if he sold 500M more then 10 times to 10 diffrent people then I would trust him on 500M.
around 1-2b I would trust someone with at least 500m in a trade.
