The idea of this post is to create a list of mistakes that people (including myself) have made, so that smart Bitcoin beginners can hopefully avoid them by learning from someone else’s experience.
I’ll start with a couple of mistakes I made some time ago, and I hope no one repeats them.
I deposited some sats on Celsius and BlockFi because they were offering around 6.5% APY, and I wanted to earn more Bitcoin.
Now I understand much better the importance of self-custody.
Another mistake I remember was mixing KYC and non-KYC UTXOs. I had bought BTC both on exchanges and via P2P, but I wasn’t using a proper wallet with labeling features.
At some point, I consolidated some of those UTXOs together… and now I no longer know which sats came from KYC sources.
What about you guys? What rookie mistakes did you make? Let's help others avoid them.
