Recently reviewing my on-chain/within-platform records for the past year, I really feel like throwing my phone away... To be honest, the hardest part at the end of the year isn't whether I made a profit or not, but "what exactly does this transaction count as." I've set a practice for myself: every time I change positions / cross chains / farm airdrops, I leave a record—transaction hash, time, amount of tokens, a screenshot at the time (or export market data), plus a note: why I did it, which oracle/price feed I used (some platforms have delays, and if you review later, it won't match and you'll go crazy).

Don't wait until the end of the year to fill in the gaps; the more you fill in, the more it feels like you're distracted while taking care of a kid: one slip-up and something goes wrong. Especially now with NFT royalties causing a lot of noise, creator income, secondary liquidity being pulled back and forth, I just want to remind myself: no matter which side you're on, if the trading flow gets complicated, reporting becomes even more complex... Anyway, I plan to develop the habit of keeping records first, as a practice for trading psychology: less overthinking, less luck, more evidence.
