Elon Musk, in an interview, argues that Dogecoin is superior to Bitcoin due to its higher transaction volume capability and lower transaction fees, which he believes makes it more suitable for everyday use. He also highlights Bitcoin's outdated design, created in 2008, which makes it ill-suited to today's fast-paced internet. Musk further argues that Dogecoin's fixed annual inflation rate encourages spending, unlike Bitcoin which may cause people to hold onto it due to its deflationary nature.
