Frequently asked questions
How detailed must records be?
Enough to reconstruct net results and FMV at each movement. Monthly summaries plus individual deposit/withdrawal rows satisfy most advisers; bet-by-bet export helps disputes.
What is fair market value for crypto?
Typically the exchange rate to local currency at the time of receipt or disposal. Many use closing price from a reputable index or exchange you actually use.
Do I need blockchain explorers saved?
Save transaction hashes and optional explorer links — hashes let you regenerate proof years later even if the platform closes.
How long should I keep records?
Match your tax statute of limitations — commonly five to seven years, longer in some cases. Keep longer if ongoing disputes or amended returns possible.
