From claim totals to BTC
After weeks of faucet claims you may hold millions of sats in a micro-wallet. Convert to BTC to compare with exchange minimums and withdrawal fees.
Rounding
We display BTC trimmed of trailing zeros where safe. On-chain amounts are still whole sats under the hood.

FAQ

- Divide satoshis by 100,000,000. Example: 50,000,000 sats = 0.5 BTC.
- Will this change after a Bitcoin halving?
- No. Halvings cut the block subsidy, not the number of sats in a bitcoin.
