How much bitcoin is illegal?

As a professional practitioner in the field of cryptocurrency and finance, I'm often asked about the legality surrounding cryptocurrencies. In particular, a question I often encounter is, "How much bitcoin is illegal?" However, this query poses a complex challenge. The legality of bitcoin or any cryptocurrency doesn't depend solely on the amount held but rather on the context and intent of its use. For instance, using bitcoin for illicit activities, such as funding terrorism or laundering money, is illegal regardless of the amount. Conversely, owning and trading bitcoin for legitimate purposes, such as investment or payment for goods and services, is generally legal in many jurisdictions. Therefore, the key is not the amount of bitcoin but rather how it is utilized and in which jurisdictions the activities occur.
