How to save on fees
- If your transfer is not urgent, pick “hourFee” or “economyFee”. The tx will arrive in 1–6 hours instead of minutes, but you will pay 3–5x less.
- Fees are usually lowest on weekends and at night UTC, when the mempool drains. If you have flexibility on timing — this is the best way to save.
- For frequent small operations use the Lightning Network — payments there are nearly free and instant. Lightning suits amounts from $1 to several hundred dollars.
- Do not set a too-low fee — your tx may sit in the mempool for a day or more. Use RBF (Replace-By-Fee) so you can later bump the fee and push the transaction through.
A Bitcoin fee is paid in sat/vB — satoshis per virtual byte of transaction size. A simple transfer weighs about 140 vB, so at the current rate you can estimate the cost in dollars: vB × sat/vB × BTC price / 10⁸.
Hashrate is the total compute power of all miners on the network. The higher — the more secure the network and the more expensive a 51% attack. It is measured in exahashes per second (EH/s), where 1 EH/s = 10¹⁸ hashes.
The mempool is the buffer of transactions waiting to be included in a block. When the mempool fills up, fees rise: miners pick the transactions with the highest fee. With an “empty” mempool you can send a transaction with a minimal economy fee and it will land in one or two hours.
A halving happens every 210,000 blocks — roughly every 4 years. At a halving the block reward for miners is cut in half. The next halving is expected at block 1,050,000. Historically, 6–18 months after a halving the main BTC rally has begun.
FAQ
What is sat/vB and why this unit?
Satoshi per virtual byte (sat/vB) is the standard fee unit for Bitcoin transactions since the SegWit activation. Virtual size accounts for the difference between the witness part and the regular part — effectively making SegWit transactions cheaper. 1 BTC = 10⁸ satoshis.
Why is hashrate measured in EH/s?
Hashrate is the number of nonce-guessing attempts per second across the network. The current ~600 EH/s = 6 × 10²⁰ ops/s. Smaller units would be unwieldy — numbers would run into the trillions.
When is the next halving?
A halving is anchored to block height, not to a calendar date. With a 10-minute average block time it works out to roughly every 4 years, but the exact date depends on hashrate (faster blocks = earlier halving). The page shows a live countdown to block 1,050,000.
Why does an empty mempool mean nothing for price?
Mempool reflects demand for blockspace, not demand for BTC as an asset. Demand for blockspace drops during low-activity moments (weekends, after pump events), but that does not mean people are selling BTC. Price and mempool correlate weakly.
