Yes. Bitcoin has a fixed supply cap of 21 million coins, but the amount actively circulating can still change over time.
To sell bitcoin in Australia, secure your account first, move BTC carefully, confirm where funds will land, keep records, and watch for scams.
Yes, you can track a Bitcoin wallet address on-chain, but you cannot see the private key. Here’s what is visible, what is not, and how to check safely.
