About Bitcoin
Bitcoin is the original cryptocurrency, created in 2009 by the pseudonymous Satoshi Nakamoto as a peer-to-peer electronic cash system. It's the largest cryptocurrency by market capitalization, secured by a global network of proof-of-work miners.

Why people send leftover Bitcoin
Bitcoin dust often builds up from change outputs after a transaction, or from small amounts left in a wallet after moving the bulk of a balance elsewhere. Because Bitcoin's UTXO model can leave odd leftover amounts, it's common to end up with a fraction of a BTC that isn't large enough to bother trading or moving anywhere in particular.
How to send it
Find the withdraw or send option for BTC.
Scanning is usually fastest from a phone; copy/paste works well on desktop.
Bitcoin has one main network for this address — but confirm your wallet isn't trying to send Bitcoin Cash (BCH) or another Bitcoin fork, which use different address formats and networks entirely.
Once everything matches, confirm the transaction. You can verify it landed using the mempool.space link above.
Fees to expect
Bitcoin network fees are paid in satoshis and scale with transaction size and network congestion, not the amount you're sending. During busy periods a small BTC transfer can carry a noticeably larger fee relative to its value — if your balance is very small, it may cost more in fees than it's worth to move at all.
