Question 1

What is the Bitcoin mempool?

Accepted Answer

The Bitcoin mempool (memory pool) is a waiting area for unconfirmed transactions. When you send BTC, your transaction sits in the mempool until a miner picks it up and includes it in a block. A larger mempool means more competition for block space and higher fees.

Question 2

How are Bitcoin transaction fees calculated?

Accepted Answer

Bitcoin fees are priced in satoshis per virtual byte (sat/vB). An average transaction is about 250 virtual bytes. Multiply your preferred fee rate by 250 to get the total fee in satoshis, then divide by 100,000,000 to convert to BTC.

Question 3

What is the cheapest time to send Bitcoin?

Accepted Answer

Bitcoin fees are lowest when mempool congestion is "Clear" (under 5 MB of pending transactions). Weekends and off-peak hours (late night UTC) tend to have lower congestion. Watch this dashboard for real-time congestion levels before transacting.

Question 4

What is a Bitcoin difficulty adjustment?

Accepted Answer

Every 2,016 blocks (~2 weeks), the Bitcoin network adjusts mining difficulty to keep block times near 10 minutes. If blocks were mined faster than target, difficulty increases; if slower, it decreases. Positive difficulty adjustments signal strong miner confidence and growing hashrate.
