Doesn't using cryptocurrencies just mean you have even more conversion fees? In the current reality where nobody else uses cryptocurrencies, you're going to be converting at both ends to national currencies (if anything at least to pay tax) Even in a hypothetic crypto utopia, there's no chance that we'll get one single currency to rule them all, so you're going to have to convert every time you pay for something (every market is going to have it's own currency)
