Onboarding for high-volume crypto: KYB bottlenecks & PSP selection

Anyone else hitting a wall with KYB for new crypto PSPs when dealing with significant volume, specifically for non-USD stablecoin settlements? We're exploring a few options for APAC regions, trying to balance fee structures and payout reliability, but the initial due diligence/onboarding process feels glacial compared to traditional fiat rails. Concerned about potential liquidity fragmentation across multiple smaller providers versus a single, robust partner. How are others navigating this, particularly regarding the trade-off between broader market access for altcoins and the operational overhead of managing numerous integrations?
