Why is it that when I send some bitcoin, I see in the block explorer that part of it has come back to another address of mine?
The bitcoin balance shown in a wallet is calculated by adding up all the UTXOs that belong to you. There’s no “balance” field on the blockchain.
Ethereum uses an account model: the blockchain directly records each account’s balance. A transfer deducts funds from one account and adds them to another.
Learning this won’t make me money right away, but it can help me avoid a basic mistake.
There’s no shame in taking it slow. Staying in the game matters more than how much you make on any one trade.
