How long is a blick?

Excuse me, could you clarify something for me? I've come across the term "blick" in a few discussions lately, and I'm wondering if it has a specific meaning or duration in the context of cryptocurrency or finance. I understand that it's not a term commonly used in these fields, so I'm curious if you've encountered it before and if so, what it refers to in terms of time. Is "blick" a colloquial expression for a specific time frame, or perhaps a misspelling of a more common term? Your insight would be greatly appreciated.
