I'm in the US and on 120V power. Which only provides a quarter of the power vs the 240V mains used in Europe, to the heat bed making it far less likely to happen. Plus, I use a surge protector for it. Nor do I run overnight prints because I don't trust ANY 3D printer. And that includes my Prusa. I'm no Bambu fanboi, but one reported case of a mini catching fire is statistically irrelevant.
That said, there is an inherently greater risk of fire with certain types of hobbies. And 3D printing is one of them.
