Anyone here mining Bitcoin? What’s your biggest concern with hosting companies?

I’m curious to hear from people who are currently mining or looking into Bitcoin mining. For those considering crypto mining hosting, what are the biggest reservations you have?

Is it trust?

Hidden electricity costs?

Machine ownership concerns?

Long contracts?

Or something else entirely?

Hosting seems like the easiest way to scale mining, but it also feels like there are a lot of unknowns if you haven’t done it before. Would love to hear real experiences, both good and bad.
