Sorry to ask, but why you just go and open cryptsy account and sell your ltc for btc and withdraw .. this should take less time then creating your first post ..or am I missing the point ?
You should read the "Why don't I sell my collateral" section here: https://bitcointalksearch.org/topic/edu-the-rule-of-no-collateral-no-loan-ignore-at-your-own-risk-577765
That is mainly about physical collateral.
But ok I dont care what you do, its just that if you exchange your ltc to btc ... will cost you nothing. Doing it your way, you have to pay interest and create topic etc ..
good luck with your business plan
In a nutshell:
Alt coin collateral is given with the anticipation of the value of said alt coin rising.
Look its just my personal opinion, but I find that as a pure nonsense when someone has 0.5 ltc and wants 0.01 btc ... and ask for a loan and put 0.5 ltc as a collateral
Maybe im retarded I dont know ... but i really dont see sense in that
