This machine accepts tons of world currencies. This will be much to the disadvantage of its owner, who will now have to try to change $20 in each of a dozen currencies to the local fiat currency. Doing this will be somewhere within a triangle of difficult, annoying, and expensive. Once owners figure this out, they will probably demand a way to program their machines to reject most currencies, just like everyone else does. Accepting "currencies from over 200 countries" is not a good thing when there aren't that many countries in the world with currency you'd want to hold. Nor does it reassure us about the machine's ability to reject counterfeit notes--owners won't be able to verify notes they don't normally use, and BTC will ensure that fraudulent depositors have low risk of being caught.
