For .ca I'd have to pick two, stablepay.ca and goldberry.ca. Both are taken in many extensions.
StablePay because stablecoins are going to get massive use and this would be a good brandable for a company that handles stablecoin payments.
Goldberry, I just like gold keyword names that make sense or are brandable. I think the gold keyword will get more popularity as the gold price keeps rising.
I also registered a few .si, like Puck.si.
I do very few hand regs these days, but anytime I see something that gives me an idea I'm still checking if domains are available.
