Yeah, with the appalling civil forfeiture concept that I hope everyone is aware of, I also feel uncomfortable with this word "suspicious."

In brief summary: If the police search your car (let's just assume probable cause exists) in a routine traffic stop and find say, $50,000 in cash in a bag, they can charge the cash with a crime and arrest it, and unlike a person, it's guilty until definitively proven innocent. I don't think that's fair. And it's a big reason that holding more than a little cash is financially risky.

On the other hand, up till now I'd argue it's more risky (just specifically in terms of potential for loss of the money) to have your BTC in Coinbase or say, FTX where mine was, than in self-custody. These notions may reverse if your crypto private keys can be seized automatically as "suspicious," and the civil forfeiture thing has proven that the police will do that.
