BlackRock says Russia-Ukraine crisis could accelerate digital currencies

We definitely saw more crypto transaction flows going in to these regions following the current situation. But one challenge to greater adoption is the off-ramping from crypto back to fiat currencies which is largely done online by centralized exchanges such as Coinbase and Binance.

Best case is if you keep all transactions in crypto, which can then be entirely managed P2P. Compromise case is P2P trading for fiat money, which may impact your rates but is better than nothing. Otherwise, you're at the mercy of the centralized exchanges that are in turn limited by compliance and regulatory considerations.

Unless the entire world suddenly decides to adopt crypto (unlikely), the fiat component will be a major challenge for greater usage.
