Dear Jetwin customers jetwin could void yours bets at anytime saying obvious error and you cant do anything against it.

You can see that jetwin voided bgerb user's bet saying obvious error, but it is not truth.

Jetwin talking about arbitrage betting, Jetwin cant void bets saying arbitrage betting, they will say obvious error.
You can prove that it was not error ()
but because jetwin has no license (like nobody has in the bitcoin gambling world) there will be no effect.
