Lately, watching various Layer 2 solutions argue about TPS, fees, and subsidies, it's lively but my first thought is: during year-end taxes/filings, who will save me with these cross-chain back-and-forth records... I would really go crazy.

My current clumsy method: every time I make a large swap or cross-chain transfer, I take a screenshot (time + amount + chain), periodically export a record of transactions from the exchange and upload it to the cloud drive, and clearly note the common addresses and remarks on-chain. Honestly, it's not to "prove how much I earn," but to avoid staying up until 3 a.m. verifying transactions during reconciliation. Anyway, I’d rather spend an extra 5 minutes now than scramble through browser history at the end of the year... it’s too stressful, I just can't handle it.
