Could you please tell me how I can recover my investment?
Forget it and move on, according to this
thread TBAR is already declared by SEC as fraudulent. If you have the TBAR token, I suggest you sell it instantly but if you were talking about its original BAR token, you cannot recover it because it was lost due to hack according to this article in
steemit. Instead of worrying about it, you are better off doing something else to recover the funds you have lost.
