Why you should use a fresh Bitcoin address for every swap
The easiest Bitcoin privacy habit costs nothing. What address reuse gives away and how modern wallets handle it for you.
Every Bitcoin transaction is public forever. If you use one address for everything, anyone who learns it once can see your full balance and every payment you ever received or made. That is like putting your bank statement on a billboard because you gave someone your account number.
What reuse gives away
- Your total balance at that address.
- Every amount that ever came in, and when.
- Links between payments that would otherwise look unrelated.
Your wallet already does the work
Modern wallets are hierarchical deterministic wallets. That is a long name for a simple idea. From one seed phrase they can produce an endless list of addresses, and they show you a new one every time you press Receive. All of them belong to you and are restored from the same backup.
So the habit is easy. Press Receive, use the new address, done.
Refund addresses too
When you swap Bitcoin on SwapPrivate, you give a refund address in case the swap cannot complete. Use a fresh address for that as well, not the one you just sent from. It keeps the refund from tying your history together.
Change outputs
When you spend, the leftover usually goes back to a new change address your wallet creates. That is normal and good for privacy. Some wallets also let you choose which coins to spend, called coin control. If you have coins from different sources, keeping them apart avoids linking them in one transaction. Ready to swap?

Quick answers
Is it safe to have many addresses?
Yes. Modern wallets create all of them from the same seed phrase. Back up the seed once and every address is covered.
Which address type should I use?
Native SegWit addresses starting with bc1q are the most widely supported and cheap to spend. Taproot addresses starting with bc1p are newer and also fine where supported.
