Higher minimum deposits.

low for who tho

Some payment methods have a flat fee, so a $10 deposit can cost them close to what a much bigger one does. I figure that’s part of why minimums creep up. Check the actual bonus terms too.

A low deposit minimum doesn’t help if the bonus itself only kicks in above a certain amount. I’d look for both written plainly.

Why's it matter?

Processing costs seem to be part of it. I’ve seen the same casino show a $20 minimum for one coin and about $5 for another, so check a few options on the deposit page before writing it off.

Minimums have been creeping up for a while now, low ones are getting rare. Not much you can do except check before you sign up.
