How much is 1000 core in usd?

Could you please clarify what cryptocurrency you are referring to when you say "1000 core"? As "core" is not a commonly used term in the cryptocurrency space, I suspect there may be some confusion or misinterpretation here. If you're asking about the value of a specific cryptocurrency in US dollars, the answer would depend on the current market price of that cryptocurrency. You can typically find this information by searching for the cryptocurrency's ticker symbol or name followed by "USD" or "price" on a reputable cryptocurrency exchange or price tracking website.
