#TradingMistakes101 The first mistake I made was when BTC first hit 109,000 I bought at that price believing it would go up to at least 150,000 right away. It didn't, but I didn't lose heart and held on and it did go above that high.

You have to buy at every significant retracement.Which of the following statements is/are correct about Bitcoin’s UTXO model? Choose all that apply.

Every single UTXO is individually signed and verified.

Users create a new output called “change” to the recipient of a transaction.

The UTXO used as an input in a transaction can be used multiple times.

The UTXO model helps prevent double-spending.

Each UTXO carries with it the entire history of its ownership.
