Seriously though, there is an actual strategy with these. A few months ago I had a note where the bankruptcy was dismissed and the borrower made a payment. That was a very rare event, however.
Because there is very limited risk (i.e. there will always be a sucker buyer at >95%), you can normally get out of the note at about the same price you paid. The true risk comes in when LC decides to charge off the notes a month or two before they normally would. The other risk is that you simply forget about the note and it ends up charging off at the normal time, preventing you from selling.
So on average, your profit might be a few pennies per note, after commissions. But when you are only spending $1.00 on a note, an 8-cent profit is an 8% gain. Multiply that by the handful of notes a day that show up on the market and you could make a few bucks a month. Enough for a Big Mac and large fries. But in all honesty, you would make a lot more money working at McDonald's for minimum wage than you would for spending the same amount of time trading these bankrupt notes.
