  2. 02 Four checks before you connect Reach the site from a bookmark rather than a search ad or a DM link. Compare the domain …
  3. 03 If it already happened Move whatever is left to a fresh wallet created on a clean device — revoking approvals i…

Reading the market

Price is the output. Learn to look at supply, positioning and sentiment — and where the numbers actually come from.
