Below is from a quick Google search, for what it's worth. $15 M US is less than a rounding error to some of these crypto companies, and Crypto.ca must be the premium crypto .ca domain there is.
As of March 2025, Crypto.com's balance sheet shows $6.933 billion in cash and short-term investments. Crypto.com generated $1.5 billion in revenue in 2024.
Coinbase has approximately $9.824 billion in cash and short-term investments on its balance sheet as of December 31, 2024.
Ofcourse just because companies have a lot of cash on hand doesn't mean they will spend it on a domain, but they easily could.
