Every time I see the words "tax/filing" at the end of the year, I get goosebumps... So now I try to stay Zen but keep a record: export the exchange transaction records and withdrawal records first and upload them to the cloud drive, on-chain just use addresses as clues, screenshot the blockchain explorer page from time to time, don’t think it’s crude, when it really comes to review, it’s more reliable than memory. Especially for someone like me who plays chain games everywhere, mints a meme small picture, can make three or four transactions with 0.8U, and it can drive you crazy when reconciling later. Recently, the "compound yield" from staking/sharing security sets has been hotly debated, I just add a note each time I layer it: where the money came from, where it went, waited 3 minutes for confirmation... otherwise I’m really afraid it will end up as a "nested doll" in the tax report. If I lose money, just consider it buying a ticket, but keep the ticket stub.
