I only take one note: When you're itching to chase a rally or add to your position, pause for three seconds and ask yourself—are you being pushed by new information (can I clearly explain why it's useful) or by emotion (fear of missing out, envy of others making money)? Recently, the "compound yield" from pledging/sharing security has been criticized as a copycat scheme. If I can't clearly explain how the risk is transmitted and who is backing the guarantee, then treat it as an emotional impulse—reduce your position first, look more on the chain, and then decide.
