I learned two things about Bitcoin today…
1. That you could create your own hardware wallet with a raspberry pi, a seed signer, and a coldcard firmware.
2. If you’re producing hashes but not producing your own blocks you are not really a miner. You are a hash provider.
Not your keys not your coins….
…OH LOOK 👀
Fannie Mae one of the biggest contributors to the mortgage crisis is accepting Bitcoin as collateral for mortgages!
Half in Bitcoiners might say things like you should diversify into the stock market as well.
But to me that’s investing into the same system that created all the issues that Bitcoin is trying to fix.
You’re either trying build a more just system or else you’re not.
Buying a tiny amount of Bitcoin like one dollar or 1,400 Sats and immediately sending it to your cold storage isn’t really a good idea.
Right now, sending an on-chain transaction costs around 0.3 to 2 Sats per byte, but that could be much higher in the future.
What that means is if you try to withdraw that $1 you put in a while back and it’s now worth a lot more in fiat, it might cost 1,400 Sats just to move that chunk of Bitcoin, which is called a UTXO.
If that happens, you could end up with basically nothing and all that money would be gone.
This is what people mean when they talk about UTXO management.
The cost of sending Bitcoin depends on vBytes, and the more UTXO chunks you have, the higher the fees.
You want bigger chunks of Bitcoin, not tiny 1,400 Sat pieces.
It’s smarter to save up more before sending it to your cold storage, or you can consolidate your UTXOs in your hardware wallet by sending all your Bitcoin to yourself. That creates one big UTXO and can save you from losing a lot of Satoshis later.
One thing to remember is that consolidating UTXOs this way lowers your privacy because it exposes your public key.
If you want to avoid that, you can get another hardware wallet and send your Bitcoin there instead. That way your public key on the new wallet stays private.
The main takeaway is don’t send a bunch of tiny transactions to your hardware wallet.
Learn UTXO management and save as many Satoshis as you can.
