Crypto is not providing faster payment rails or better remittance services

Since crypto assets cannot function as a currency they are not useful in building payment rails or remittance services. Crypto assets can be used as an intermediate asset in which trades can be settled in, but this does not serve a technical of financial purpose and simply introduces an unnecessary conversion step for no reason.

If a person wants to send money abroad, say from US dollars to Indian rupees they would typically use a service like MoneyGram or WesternUnion. These services charge a transaction fee and do a direct swap of dollars to rupees from the reserves the company holds in both currencies.

If one postulates using a crypto asset or stablecoin as a means to do remittances then they are stilled faced with the last leg problem. Their relative in India still has to convert the crypto asset into the local currency to buy domestic goods and services since supermakets and stores don't accept crypto assets. So instead of a dollar-to-ruppee conversion we would hypothetically do a dollar-to-bitcoin-to-rupee conversion. This introduces price-risk, counterparty-risk and unnecessary conversion fees to accommodate the extraneous third exchange. This is unnecessary complexity and likely more expensive, for no reason.
