Sourcing vs. seasoning for crypto funds
**Sourcing** is documentation: proving where down payment funds came from and that they're yours.
Sourcing is documentation: proving where down payment funds came from and that they're yours. Seasoning is a substitute for documentation: letting funds sit in a bank account long enough (typically two statement cycles, 60–90 days) that their origin no longer has to be explained. Every seasoned dollar is a dollar somebody couldn't — or didn't bother to — source.
Why crypto sources beautifully — and seasons badly
Public blockchains are permanent, timestamped ledgers: ownership can be proven cryptographically and holding history is inspectable to the block. In principle, a BTC down payment is more traceable than most checking accounts. In practice, the typical DIY cash-out destroys that at the last step — a casual exchange sale, chunked withdrawals, money spread across accounts, no records. The underwriter can't use "trust me, it was Bitcoin," so out comes the calendar.
The fix is structural
You don't fix this with better screenshots after the fact. Verify wallet ownership before you offer, convert once at closing through a venue that papers the trade, wire once, directly to escrow. That's RealOpen's convert-at-close flow — the source-of-funds question is answered before it's asked.
