Speculative video, without any figure. Are Argentinians investing in gold, dollars or any other security? No data at all provided. presuming that crypto currencies will boost because a country has hyper inflation is not logic. The total capital in crypto currencies is growing https://coinmarketcap.com/charts/ but will this triggers massive adoption? I doubt so. There are still features to be improved as authentication, transaction speed or trust. There will not be a real financial crypto market until no exchange is done between cryptos and FIAT money. Adoption implies real usage, which means that daily purchases are done in crypto currencies (we still don't have that any project capable of that; we still miss infrastructure on off network areas; we might only see adoption with satellite global coverage) Adoption is a matter of years, but it will not be due to a fail economy. It will be due to improvements on the current developing industry (Nowadays you can't pay with crypto currencies, you need to first exchange to FIAT and pay exchange fees)
