Excuse me, I'm curious about shorting cryptocurrencies on Kraken in the United States. Is it possible for individuals or traders to engage in short selling on Kraken's platform within the US jurisdiction? I understand that shorting involves betting on a decrease in the value of an asset, and I'm wondering if Kraken supports such a strategy for US-based users. Additionally, are there any restrictions or regulations I should be aware of before attempting to short on Kraken as a US resident?
