What a crypto wallet actually controls
A wallet does not hold coins like a billfold. It holds keys. Lose the keys, lose the ability to move the coins — even if the blockchain still lists them.
Markets
What an ETF holds (and what the ticker does not tell you)
The three-letter ticker is a wrapper. The holdings file is the product. Leverage, income, and “AI” in the name are not the same job.
A stock is a company. An index is a scoreboard.
Search traffic still confuses “the market” with a single ticker. An index is a formula. A stock is a claim on one business.
