Remittances have been shown to not actually be better with bitcoin. [1] [2] [3]. I can send 2000 USD to India using TransferWise and they will only charge me 17.84 USD. That is a 0.89% fee using a reliable mechanism and I know my recipient will have their native currency in their bank account within a couple business days. Compare that with opening an account on a US bitcoin exchange, sending money there (time delay), buying bitcoin (exchange fee), opening an account in india (requires verification and linking a bank account), sending the bitcoin over (time delay), converting the bitcoin to rupees (time delay, exchange fee, volatility risk), then sending the money to the bank (another time delay).
