Well I have plenty of friends in Argentina, and Ethereum is helping them live through hyperinflation.
Their currency is plunging, their banking system is corrupt, so these are their options:
1. Trade Pesos for USD on black market exchanges. Hide cash in safes & under mattresses 2. Purchase Dai or other stablecoins. Keep money in multi-signature vaults, earning interest through lending protocols.
Plus, cryptocurrencies allow many of them to work for foreign companies and get paid directly in stablecoins.
