Due to fluctuations in currencies, in conjunction with mark-ups that financial institutions provide on foreign currency transactions, purchases in a non-local currency effect the consumers and the suppliers substantially. This is particularly true for hotel chains and airlines that provide services on a global scale as it leaves them prone to swings in currency valuation. This has significant impacts on their P&L.
Having a standard currency or token would not only eliminate the need to pay significant conversion fees but would also minimise the risk of exposure to significant fluctuations in currency. Such a universal token would effectively ensure a more accurate representation of income for the supplier and expense for the consumer.
