Having that explanation, you lost half of the price of Litecoin in based market's price. Is your friend working for that exchange or he has no idea what happened to you?
It only takes a few seconds to know this was a scam. The website is poorly designed, doesn't have a certificate, they have the word "sex" in their website name, and they use a cheap .vip domain. How many more red flags did you need to see before you determined this was a scam? $12k is a big loss but I can't really feel too sorry because it was such a stupid mistake for you to trust them with any amount of money.
Correct. The domain was even suspicious.
