I'm always surprised to see that some people are still buying BARs (for a strange reason ) on Hitbtc. Ho is it possible

You'll have to ask Hitbtc that question, it is rather strange. Also sad that people don't even bother to check what they are investing in.
Its been nice and steady at 32 cents. A great profit of at least -50% for everyone who went in at ICO
Nothing is profitable right now, unless you are a very clever day trader. Crypto as a whole has sunk for the time being. We have to wait for a market improvement.
