Have your Bitcoin transactions ever gotten stuck in the mempool? With over 200,000 daily transactions on the Bitcoin blockchain, delays are common—especially during peak traffic. This guide explores proven methods to accelerate unconfirmed transactions, including free and paid tools.
Why Bitcoin Transactions Get Stuck
Key Factors Causing Delays:
- Blockchain Congestion: High demand leads to backlog in the mempool.
- Low Fees: Miners prioritize transactions with higher fees (currently ≥ 0.0001 BTC/KB).
- 1 MB Block Size Limit: Restricts how many transactions fit per block.
