I know nothing about this but have a story, though it was all over the press in December.
A friend of my Son, and 8 friends made 488 million pounds from a single office in one day split by the money invested, Sons mate was ring leader and got 74 million, the lowest share was 22 million.
If you read the December press it states US lawyers were trying to build a case, but this was earlier in the year, and no case was found. They have all the money.
They were betting on oil prices.
