If I make a temporary profit from a rebalancing bonus but ultimately lose money, will I be subject to taxation?

It is subject to taxation. As a general rule, income earned from cryptocurrency is classified as miscellaneous income. Miscellaneous income cannot be aggregated the profit and loss against other income, but can be aggregated profit and loss against other income if the income is classified as the same miscellaneous income. For example, if you use only one currency pair, you cannot aggregate the profit and loss, but if you use the specified currency pair, you can aggregate the profit and loss, because they are miscellaneous income, and the amount of profit offsetting the currency pair is taxable.
