An NFT just sold for about what, $60 million US? So $15,000 CAD for diet.ca looks cheap if you're in that disposable income bracket where 15k would otherwise just be sitting in your account with nowhere to go. Could still be an investment, or with the traffic it gets could probably be easily a simple PPC or affiliate site related to that subject. And when looking at crypto and blockchain developments, who knows what else DIET could come to mean.
