Just a question I don't know. Is the Bitcoin a digital currency or a digital good?
At a technical level, it is neither. It is simply a ledger entry.
Beyond that, it would depend on how your government chooses to classify it.
This is quiet accurate answer in technical speaking. But nowadays. Crypto users knows it as a digital currency just like what you always saw on cryptocurrency exchange platform. Bitcoin as a currency is the most simplest description to easily understand what is the main use of it.
