Cost basis vs current floor for tokens you still hold. Cost basis = your most recent on-chain buy price for that token. Mints, free claims, and gifts show as ?.
Floor is the cheapest XTZ-denominated active listing on that exact token (any marketplace). Sales paid in altcoins (DOGA, USDC, PEPE, …) are excluded — comparing a token-priced buy to a tez floor is misleading.
Heads-up: some artists set sky-high “make-offer” BIN listings (e.g. 2,000,000 ꜩ). Those inflate the floor sum but the math is correct — that's the actual on-chain ask.
