Mastercard recently announced that it has plans to natively support cryptocurrencies that meet certain criteria. For the company, as for everybody else, it's clear there is money to be made in cryptocurrencies.
The problem for Mastercard is that it requires that the cryptocurrencies it works with are not excessively volatile and keep KYC controls. Virtually no cryptocurrency meets these criteria. Even if widely used cryptocurrencies became somewhat stable in price, it's not clear how KYC would be implemented on users of decentralized networks in which anyone could participate, nor how basic anti money laundering regulation would be enforced.
