There won't be anymore news.  These HYIP sites are a dime a dozen.  Check out the "blacklist" section of http://www.hyipexplorer.com/  It currently has over 32,000 records, of which BT represents just 0.003%.  BT differed only in that they advertised on Reddit and Blockchain and justified their earnings with mining.  Other than that, it was a cookie cutter HYIP.  There is no reason to assume authorities will pursue BT over the tens of thousands of other concurrent scams.  

The matter is further clouded by the victims attempts to collaborate, unable to even subtract the correct numbers in question, despite being corrected every time the issue is raised.  Deposits - withdrawals = money lost.  All victims first attempts to collaborate on this point always include "value of shares" which in my case, makes my losses appear double of what they actually are. Additionally you have multiple victims taking the lead, so they all have their own aggregate of losses combined from a different sets of participants.

Take away: We've all been had, authorities won't even investigate, they're never going to get caught, even if they did, they don't have enough of the money to pay people back.  Write this off as a lesson learned, and be skeptical of "too good to be true" in the future.

Cheers!
