I'm from Romania.
That's the final notice ( deadline Oct 1st ). KCC is legit from what I see. I'm expecting some notice from Kraken and also from Bittrex ( only for Bittrex US users).
I wouldn't be surprised at all to get something from Binance also..( but there are two separate entities, US and Global).
I'm from European Union too (France) but I didn't get anything from them sadly. I don't know how many people are eligible to the compensation, but the amount shared and distributed seems to be rather large. I don't think you will get this kind of reward from Bittrex since they are already closed and will only share the remaining money they have between customers who had still funds onto their account when they've closed their doors.
The Commission ordered Poloniex to pay $8,484,313.99 in disgorgement, $403,995.12 in prejudgment interest, and a $1,500,000 civil money penalty to the Commission. The Commission created the Poloniex Fair Fund pursuant to Section 308(a) of the Sarbanes-Oxley Act of 2002, so the penalty paid, along with the disgorgement and interest paid, can be distributed to harmed investors.
