I invested in btcjam.com and lost a lot on their loans and now they are closing their website Don't lend money to anyone in a foreign country unless you are sure you will be able to go to that country and legally get your money back.

Especially pointless getting a legal letter saying I am owed .5 btc from someone who lived in Venezuela and has since moved countries. Or people who get a fake or stolen phone number or address or id for verification.

These types of sites eneviatbly end in lenders being scammed,no matter how diversified the site says you are.
If Bitcoin doubles and someone in a far away land got btc from you before hand converted to fiat and now owes you twice what they borrowed,it will never work out.
