I fear that cryptocurrency will be even worse: imaging how big the blockchain can became if used as main currency; who can really operate on it the if not very few super-giants that offer "broker services" like today's online wallets services? Also see the actual hw trend: we get more and more closed platforms more and more stuffed with proprietary fw, how can you trust even your UEFI machine or even fw-enabled keyboard, no matter how strongly encrypted your files are... You can't even trust your mobile phone nearby your keyboard since we have enough POCs of how to determinate keys pressed with a simple audio analyze... The sole currency I can trust is paper one: it can be stolen, sure, but if you have it in hand and is legal to use it you can exchange money so exchange values/goods without big dictators in the middle, it doesn't matter if they act for good or bad.
