Why is it still so hard to implement a simple crypto payment flow?

Been digging into this while working with a few early-stage products, and most setups break at the same points:

– Card → crypto (USDT TRC20) isn’t seamless
– Minimum invoice limits kill smaller transactions
– Settlement delays mess up cash flow
– KYC requirements slow down onboarding
– Existing gateways feel built for large volumes, not MVPs

Feels like most “solutions” are not designed for:
• indie builders
• SaaS tools
• small ticket size products

Curious

1. What kind of crypto payment flow are you trying to set up?
2. Where exactly does it break for you right now?

Trying to understand real-world use cases before building anything further.
