I think it's better to wait and see what it will happen and who said that them are stolen btc, we don't know...
Even if founds are not really stolen a person who are giving them away told us that he's a BFXHacker.
Even if he is a liar. You should not take a part in such a giveaway.
it's like:
-"I STOLE MONEY AND WANT TO SHARE!"
-"Oh well, I don't believe you stole it so give it to me that's fine because I don't really think you are saying the truth... "
-"Yes, I hacked BFX"
-"No, I don't trust you, give me some coins please"
WTF !!! BITCHES!
