I recently summarized a version of position management in plain language: Don’t let any single trade have the right to determine whether you can sleep well tonight.

If you can’t hold spot positions, don’t go all-in on your beliefs; buy in multiple times, keep some bullets.
For futures, don’t hold on too tightly either; no matter how small the leverage, first figure out “the worst possible loss,” or else a liquidation is basically because you didn’t set a limit.

By the way, when hardware wallets are out of stock, phishing links also become more common; the more emotional you get, the easier it is to click the wrong one.
To put it simply, position management and security habits are the same word: limit.
Don’t leave your limit to the market, and even less to a link.
That’s all for now.
