On May 7 at 9:13 PM EST, Binance—the world's largest cryptocurrency exchange—announced via its official social media account that it had temporarily suspended Bitcoin (BTC) withdrawals due to an overwhelming backlog of pending transactions. The platform assured users that its team was working on a solution and aimed to restore services promptly.
By 10:39 PM, Binance followed up with another update: a surge in Bitcoin network gas fees had left numerous withdrawal requests unprocessed, as the exchange’s preset fees failed to account for the sudden spike. The team reiterated efforts to expedite pending transactions.
Understanding the Bottleneck: Gas Fees and Blockchain Congestion
A cryptocurrency analyst explained to Pengpai News that every blockchain transaction requires gas fees paid to miners or validators. Exchanges typically charge a fixed withdrawal fee (e.g., 0.0005 BTC per transaction). However, during network congestion, actual fees skyrocket, far exceeding preconfigured rates.
Key factors behind the disruption:
- Blockchain Scalability: Bitcoin blocks are capped at ~1MB, processing only a few thousand transactions every 10 minutes.
- Gas Fee Auction: Miners prioritize transactions with higher fees, leaving lower-bid requests stuck in queues.
- Recent Surge: Heightened BTC network activity drove gas fees to unsustainable levels, outpacing Binance’s preset thresholds.

Repeated Service Halts and Earlier Outages
This wasn’t Binance’s first withdrawal pause that day. At 11:07 AM EST, the platform cited Bitcoin network congestion as the reason for suspending withdrawals, briefly resuming services in the afternoon before evening issues resurfaced.
Historical Context: Binance’s Operational Challenges
- March 24: Binance halted spot trading globally after its matching engine glitched during trailing stop orders. CEO Changpeng Zhao attributed the 30–120 minute outage to a debugging incident reminiscent of early computing’s literal "bugs."
- CFTC Lawsuit: Late March saw the U.S. Commodity Futures Trading Commission sue Binance and Zhao for allegedly operating an illegal derivatives exchange. Binance contested the charges as "based on an incomplete factual narrative."
FAQs: Addressing User Concerns
1. Why did Binance pause Bitcoin withdrawals?
High transaction volume and underestimated gas fees led to unprocessed withdrawals, prompting temporary suspensions.
