El-Ahmad has linked Barnsley FC with a crypto currency bit coin "company" called HEX as sponsors

I haven't a clue what the jargon means on the Official Website announcement but initial research suggests HEX could well be a Ponzi Scheme, similar to a pyramid scheme, where existing investors are paid from funds gathered from new investors, the process continuing until new investors run out and the scheme collapses leaving only the early investors quids in from other peoples' money.
These scams often collapse very quickly so, morals notwithstanding, it is essential that El Ahmad/ BFC is paid up front as it could be gone by mid season.
Smacks of last minute desperation to me.
