Why would a time traveler announce himself to answer questions? If you can't offer proof, you should already know nobody believes you, so what's the point?

If you know of a better way for a "time traveler" to earn some satoshis on his return home, please let me know.
You can buy a car with satoshis where I come from.

если мы договоримся и представим что он говорит правду, то у нас будет возможность проверить её методом докозательства работы. все что не сработает, это ложь. Всё просто. биткоин инструкция.

if we agree and imagine that he is telling the truth, then we will have the opportunity to check it by the method of proof of work. anything that doesn't work is a lie. Everything is simple. bitcoin instruction
True, if he can tell us what the bitcoin hash will be 6 hours from now then we know he is a time traveler. Its not like we know what the transaction order or which transactions from the mempool would be used so its not a financial prediction.
