US-based users face unique withdrawal issues tied to federal banking regulations (ACH holds) and individual exchange security protocols. ACH Withdrawal Hold: "Why can't I withdraw my ACH deposit from Gemini immediately?" or "Coinbase 'funds on hold'." Reason: ACH deposits take several business days (up to 7) to settle. Exchanges allow trading immediately but block withdrawals until the funds are irrevocably cleared. Solution: Use Wire Transfers for funding if you require instant withdrawal access, as they settle faster. Otherwise, you must wait for the mandatory hold period to expire. Account Restriction: "Why is my Coinbase account restricted from sending crypto?" This often relates to an attempted high-risk transaction or KYC discrepancy. Solution: Contact the exchange's dedicated support to clear the specific flag. Having tax documents or proof of income ready can expedite the process. USA Account Restriction Help: 1-888-825-6148
