0.001 BTC to USD

0.001 BTC is worth … at CoinGecko's live price. It's exactly 100,000 sats, also called 1 mBTC (one millibitcoin).

What people use 0.001 BTC for

0.001 BTC is a typical size for a first purchase, a test withdrawal to a new wallet before moving more, or a small recurring buy adding up. It's also where Bitcoin's fee model starts to matter.

Network fees at this size

Bitcoin's network fee depends on the transaction's size in bytes, not on the amount. A simple payment is about 140 vbytes:

• At 5 sat/vB the fee is about 700 sats: 0.7% of 100,000 sats.
• At 20 sat/vB it's about 2,800 sats: 2.8%.
• At 50 sat/vB, on a busy day, it's about 7,000 sats: 7%.

The percentages hold at any bitcoin price, because both sides are counted in sats. So for amounts like this, check the fee before sending, avoid repeated small withdrawals from an exchange, and consider the Lightning Network for payments. The network fee calculator shows the current dollar cost for any fee rate.

Using it as a test transaction

Sending a small amount first to check you have the right address and network is a good habit before moving a larger sum. Wait until it arrives, then send the rest. More in before you send crypto.
