I wanted to try BTCJam too, i just fear that they go away with what you invested :/
beware most people in btcjam using false identities and go after them to get loans. they will seek trust + first to gain confidence after that they will go and scammed you
yups always look their trust rating if you want to lend
I think the trust could be misused dude I had several times lent bitcoin to users who have high trust and they cheat me go with my bitcoin and did not return there are people who deliberately cultivate trust them so many other users who believe later when a certain time. He will lend larger bitcoin then go out
In my own opinion, lending business is not viable in bitcoins as it is anonymous and we can expect there are a lot of scammers in the community, if you are just lending with a little interest then the risk is higher, you better invest in bitcoins and hold, safer than lending.
