Could you please elaborate on the steps involved in purchasing Bittensor in Canada? I'm particularly interested in understanding the registration process for choosing a suitable cryptocurrency exchange, the verification procedures required, and the methods of funding the account. Additionally, could you explain the process of searching for Bittensor on the exchange, placing an order, and executing the trade? It would also be helpful if you could mention any fees or commissions associated with the transaction and any safety measures to consider while making the purchase. Thank you for your assistance in this matter.
