Exchanging BTC (bitcoin) for LTC (litecoin) How can I safely exchange BTC for LTC? I've found a website called Changelly. Does anyone have any experience with this website? Are there other websites/ways to safely exchange cryptocurrency? 

I want to make sure that if send BTC to a specific person, then they'll send me the corresponding amount of LTC.
