What is it supposed to do? Does it actually do that? What else does it do, intentionally or unintentionally? Who benefits from it, and who pays the costs? Is this exchange worth it for those paying? These are basic questions we should ask, not just about cryptocurrencies, but about the finance sector in general. When investment firms cause recessions or famines as a side-effect of enriching themselves, we have to ask if they're worth tolerating or if governments should drastically tighten regulations. Cryptocurrencies are just the low-hanging fruit. The whole tree is worth shaking.
