🚩 Sources you should AVOID (and how to spot a bad resource)¶

This bibliography is curated, but you'll spend more time on the open internet than in these books. The beginner's #1 mistake isn't a bad trade: it's trusting the wrong source. Learn to filter.

Red flags to discard a resource instantly

If a resource, account, or "expert" meets any of these, close it and move on:

Promises fixed or guaranteed returns ("X% a month", "double your money"). In crypto nothing is guaranteed; whoever claims it is lying or doesn't know.
Rushes you to buy NOW out of fear of missing the rally (FOMO). Urgency is a sales technique, not analysis.
Sells a VIP group, paid signals, or a "secret" course. The real knowledge on this list is free or costs about as much as a book, not a monthly subscription.
Promotes a specific coin without disclosing that they own it. Always look for the conflict of interest or shill: if they profit when you buy, they're not neutral.
Uses an exchange referral link as hidden payment: they collect a commission for every person who signs up.
Asks you to send crypto to "multiply it". 100% scam. Nobody sends back double what you send. Ever.
The "expert" only exists on TikTok/Telegram/Instagram and has no verifiable written work (book, paper, documentation, repository). No trace, no credibility.

Golden rule

If someone makes money because you buy what they recommend, they're not an educator, they're a salesperson. The sources on this list don't sell you the coin; they teach you how to think.

Mini-exercise: the 3-question test

Before following any new account, ask yourself:

How does this person make money?
What do they lose if their advice fails? (skin in the game — do they risk their own money?)
Do they ever admit they were wrong, or do they only show wins?

If you can't answer all three, don't follow them.
