Probably a good idea. Bad consumer debt like you are taking on usually sells for about 3% of the principal amount. It looks like you have 0.064 BTC loaned out in principal which would make the value of your loan portfolio worth about 0.00192 BTC. Given that you probably do not have solid contract with an identified borrower it might be a stretch to value the portfolio that high. If you can get back 1/2 of the BTC you've loaned out at this point you will be beating the odds. Surely you won't find buyers to pay a premium for it.
