nostr:npub1dmcd5wqd3yku05svp6xqk5gyywek4cgg0w3dk63tcu0rmjxnanns5xutjm if I am using the 'Send Dollars' feature in strike and sending to a Bitcoin wallet, and choose the 24 hour selection, at which time is the spot price used to calculate the amount of Bitcoin sent? Would it be when the transaction is initiated or when it is actually complete?
