In Australia, videos showing the TravelByBit double-spend attack virus are worrying many retailers. This viral video only shows how this particular payment processor was affected. TravelByBit currently supports both BTC and BCH, but the platform may no longer support these two cryptocurrencies. It is reported that this video was created by the well-known BCH supporter Hayden Otto. At present, TravelByBit has not yet determined when these two cryptocurrencies will be removed, but Caleb Yeoh, founder of TravelByBit, said that BTC, BCH or other blockchains are not suitable for retail sales points.
