This is as nonsensical as Chainalysis' "heuristics". You "would guess" that certain Strike transactions are Non-KYC btc purchases. You can guess all you like, but you'd often be wrong. The best way to defeat this heuristic would be to use Strike to send money between friends for all sorts of things. Start telling people about Strike as a better Venmo, Zelle, CashApp, etc. Just as someone once told you about those other apps.

Otherwise, stick to cash only, p2p deals on the street. This, however is not always an option for everyone.
