In a word: no.

Crypto isn't a Swiss pocket knife. It's simply a payment method. You need the entire financial architecture in place for the payment tool to be effective. That includes a market, parties who want to transact in crypto, goods to buy, means to transport the goods, and methods by which to deliver services. Just having two crypto wallets to send back and forth doesn't prop up a country's economy or put groceries in the stores to feed people.
