Could you please elaborate on the process of acquiring TOTO coin? Are there specific exchanges or platforms where one can buy it? Are there any requirements or restrictions to be aware of before purchasing? Additionally, what are the steps involved in storing and securing TOTO coin once acquired? Is there a minimum investment amount, and if so, what is it? I'm also curious about the fees associated with buying and selling TOTO coin, and if there are any promotions or discounts available for new users. Thank you for your time and assistance in answering these questions.
