Not all of the cryptocurrency behave as a Ponzi scheme even if many do. It also happens to be the most convenient way to transfer money between myself & the foreign friends I have—especially with Monero & Zcash hiding the transaction like cash would. I mostly use cash daily but if I have to do it digitally, I would rather it not be logged thru the government, some US-based tech firm, & all their third-party advertizing affiliates as is the case with credit cards and other mobile apps.
