Did you know newly mined #bitcoins can’t be spent immediately?

A miner's block rewards must wait 100 blocks before they become spendable.

Did you know #bitcoin can publish data without creating spendable coins?

OP_RETURN is an output in a transaction, but is not in the #utxo set and therefore can't be spent and stays on the chain forever.

Did you know #bitcoin can make money wait?

Bitcoin’s developer docs describe `nLockTime` as the earliest time a transaction can be added to the blockchain, so miners and nodes should not include it until a specified block height or time is reached.

And that's why a transaction can be fully signed and cryptographically valid, yet still not eligible for inclusion until a future block height or time.

That is programmable money not just by owner, but by time.

Did you know that a #bitcoin seed passphrase doesn’t fail if you type it wrong?

Your wallet won’t show an error.

It simply opens a different valid wallet.

Did you know that #bitcoin fees don't really relate to the amount of Bitcoins sent?

Bitcoin fees don’t depend on how much BTC you send.
They depend on how much blockspace your transaction uses, measured in virtual bytes (vbytes), and the current fee rate in sats/vB. (fee = vbytes × sats/vB)

So a $10 payment and a $10M payment can cost roughly the same if the transactions use similar vbytes.

❓Did you know that a normal #bitcoin payment usually pays two people?

- the recipient
- and yourself, into your change address

Most users see payment and fee, but don’t even notice the second payment. That is actually the unspent transaction output - #utxo

Did you know that your #Bitcoin wallet balance is a UX illusion?

Bitcoin doesn’t have balances! It has scattered unspent outputs called #UTXO, that your wallet adds up for you.
