Reads the dated futures of Deribit for BTC or ETH and compares each expiry with a spot price whose source is always named in the answer, because a basis computed against a different venue than the future is a different number. By default the Deribit index is used, which sits on the same venue as the contract; choosing a spot venue instead is possible and is then flagged, including the case where that venue quotes in USDT while the contract settles in USD. Annualization only happens above one day
