1. Understand a base knowledge of security and privacy, own your keys.
  2. Do not let yourself be lead by charlatans and "crypto influencers" who are just in it for money. Follow the technology not the price.
  3. Don't be shy, speak out and ask things.
As for the basics: Understand addresses, wallets, difference between hot and cold. Custodial and non-custodial, etc. Understand how to make a transaction. Learn the Lightning Network afterward.
