Onboarding Friction for EU Traders and Funding Options

Curious if others are finding the onboarding process with certain regulated brokers and payment service providers (PSPs) in the EU increasingly cumbersome. Seems like every few months, the KYC/AML hoops get higher, especially when dealing with non-standard funding methods or larger capital allocations. It's not just the initial signup, but ongoing re-verification requests that can be disruptive.

Specifically, what funding methods are proving most reliable and efficient for moving capital in and out of prop accounts or brokerage accounts in the current climate? I've seen some PSPs slow down significantly, leading to missed opportunities when needing to deploy capital quickly. Any thoughts on mitigating these bottlenecks without compromising security?
