Noticed this disclaimer at the bottom of the page:
In compliance with AML regulations, we reserve the right to hold any deposits that appear suspicious.
So what exactly is "suspicious"? Seems like a pretty broad umbrella that enables you to hold cash if you so choose.
The right to hold suspicious deposits is simply to comply with federal law. We will ONLY hold a deposit if we are filing a suspicious transaction report with FinCEN. Financial reporting is taken very seriously and is not something that can simply be thrown around as an excuse.
