10K is the threshold for a CTR, (AKA "Cash Transaction Report" to FINCEN). A report sent from a bank to FINCEN automatically for every deposit of over 10K in "Cash Equivalents")

This requirement also applies to other businesses operating and or providing services as "Financial Institutions".

For example, as most of you know Simon Mall now allows up to 25K of VGC purchases per day, (but once you cross that 10K threshold your SSAN and DOB is required on a different form than their normal 10K max form), for a proper CTR.

There's so much misinformation and misunderstanding about this topic on the Internet where this MS* Game/Hobby is discussed it's scary,, LOL...
