Year-end tax reporting isn't most afraid of the tax rate, but that you have no idea what you've actually done... My current clumsy method: every time I recharge/withdraw/transfer on-chain, I take a screenshot, export a CSV from the exchange and keep a copy, and label the same address with a clear note of "what it's for" on-chain, otherwise after a couple of months seeing a string of hashes will really make you forget. And don't be superstitious about "using tools to automatically summarize when the time comes," honestly, with more addresses and cross-chain activity, tools can only give a rough estimate, in the end, it's still up to you to reconcile.

Recently, there's been a heated debate in the group about privacy coins and the boundaries of mixing compliance. I just have one sentence: if you want privacy, that's fine, but don't delude yourself into thinking the records will disappear. When you really need to explain the source and destination, your future self will be the one crying. Anyway, I prefer to make things a bit more troublesome now rather than staring at a bunch of "anonymous freedom" and zoning out at the end of the year.
