In most territorial tax jurisdictions, is crypto day trading considered foreign-sourced income?

If I move to a territorial tax jurisdiction and earn money by frequently buying and selling cryptocurrency from home, would that income typically be considered foreign-sourced if the exchange and banks I use are located in a different country?

If that income isn’t considered foreign-sourced, what if I create a company (an investment firm) in a country with 0% corporate tax and then receive dividends from that company while living full-time in the territorial tax jurisdiction—would that change whether the income is now considered foreign-sourced?
