What does "not your keys, not your coins" mean?

When an exchange holds your bitcoin, they control the keys. True ownership means holding your own private keys via a personal wallet.

How can you verify a Bitcoin transaction is real?

Block explorers let you search the public blockchain and verify any transaction, address, or block independently.

How many confirmations are considered the gold standard for large transactions?

How to Verify You Own Real Bitcoin

6 min readarticleIncludes quiz · 3 questions

When you buy Bitcoin on an exchange, how do you know it's real? When you transfer it to your wallet, how do you confirm it actually arrived? One of Bitcoin's greatest strengths is that you can verify everything yourself — no trust required.

Step 1: Understand the difference between IOUs and real Bitcoin

•When you "buy Bitcoin" on an exchange, you often hold an IOU — the exchange's promise that they have your bitcoin. This isn't the same as holding real bitcoin in your own wallet
•Real ownership means you control the private keys. The phrase "not your keys, not your coins" exists for a reason
•To truly own bitcoin, withdraw it from the exchange to a wallet where you control the seed phrase

Step 2: Use a block explorer to verify transactions

•A block explorer is a website that lets you search the Bitcoin blockchain
•Popular explorers: mempool.space, blockchair.com, blockchain.com/explorer
•After sending bitcoin to your wallet, copy your receiving address and paste it into a block explorer
•You'll see the transaction, the amount, the number of confirmations, and the exact time it was recorded on the blockchain

Step 3: Check confirmations

•1 confirmation means your transaction is in a block
•3 confirmations is considered safe for moderate amounts
•6 confirmations is the gold standard for large amounts
•Each confirmation means another block has been built on top of yours, making it exponentially harder to reverse

Step 4: Verify your wallet balance independently

•Your wallet app shows your balance, but you can independently verify it using a block explorer
•Enter your public address (never your private key!) into the explorer
•The blockchain is the ultimate source of truth — it cannot be faked
•For maximum verification, run your own Bitcoin node and validate the entire blockchain yourself
