NETWORK FEES

Why We Charge a Service Fee

A transparent explanation of how fees protect your withdrawals and keep the network reliable.

OIO.SO uses the Bitcoin mainnet. Every withdrawal is a real on-chain transaction. Bitcoin miners charge a fee for every transaction — and that fee changes depending on network congestion. Our service fee ensures your withdrawal never fails.

WHY 5% AND NOT LESS?
🔬 Network Stress Test Results
During internal testing under Bitcoin network congestion:
→ At 3% fee — 3% of withdrawals failed due to insufficient miner fee
→ At 5% fee — 0% withdrawal failures
→ At 5% fee — large withdrawals (up to 1 BTC) completed reliably
⛓ Bitcoin Miner Fees Are Unpredictable
Bitcoin network fees spike during high-demand periods. A fixed low fee that works today may fail tomorrow. The 5% buffer absorbs fee spikes and guarantees delivery.
📈 Larger Withdrawals Are More Efficient
A 5% fee on 50,000 sat = 2,500 sat
A 5% fee on 500,000 sat = 25,000 sat
Withdrawing more at once reduces your effective fee rate significantly. We recommend accumulating before withdrawing.
