The infrastructure of both payments for goods and services, and for storing your assets.
As of now, paying for goods and services with cryptocurrencies is relatively risky; it's hard to get recourse if you're scammed; and the standard credit card infrastructure with chargebacks and fraud protection is comparably more trustworthy.
As of now, storing cryptorcurrencies is risky. And I'm not even talking about the shady brokers/exchanges that can steal or lose their customer's money. You can store it yourself as well as you can - but, as it turns out, most people aren't that good at storing it securely, so all kinds of risks and breaches (e.g. hacking your devices to get access to your secrets) are more common than for bank accounts but, also, the consequences are more severe - if your bank account gets drained in an identity theft attack, very often these funds are recovered or compensated, not so with crypto. So again, the existing financial infrastructure with regulation, FDIC or similar insurance in case of fraud or insolvency, mandated consumer protection in case of scammed credentials - it's more trustworthy than the commonly used processes&procedures&infrastructure of crypto storage.
