AML compliance for digital banking / crypto exchanges when moving funds?

Hey everyone, still pretty new to the deeper dives into offshore structures, especially for the purpose of asset protection and diversification. I've been reading up on AML/KYC requirements for various digital banks and crypto exchanges when moving larger sums.

My question is, for those of you who use these platforms in conjunction with an offshore company for trading or holding, how do you handle the source of funds declarations, especially when the funds originate from multiple sources or are a mix of traditional and crypto gains? Is there a common best practice to avoid unnecessary red flags or prolonged holds without sacrificing compliance? It seems like a potential minefield if not handled meticulously.
