Kinda reminds me of Kristina Williams vs Heather Hardy. Kielholtz has hype but I don't think she is actually good at fighting. Veta at +195 is valuetown IMO
I don't think you can compare Kielholtz to Hardy. Hardy can't grapple, is a boxer (who started sport as an adult to get in shape... yup, that story again) doing MMA because she needs money; Kielholtz was a member of the Dutch Judo team as a youth. Being a pure boxer (and a sloppy brawler of one at that), Hardy had enormous problems dealing with kicks vs Williams; Kielholtz is an experienced kickboxer, Bellator kickboxing champion, she won't be phased by kicks, quite the opposite.
Hardy struggled to beat the can Bellator gave her in her first fight, losing at least the first round; Kielholtz dominated the cans she's fought in Bellator so far, winning every round.
Arteaga's scramblyness on the ground is my only concern but it's not like she presents a lethal submission threat. Kielholtz does use her judo more than I'd like to see but to be fair, it's helped her dominate her Bellator bouts so far, and I still think she's more likely to come out on top in grappling exchanges in the fight. Just some questions about experience and decision making maybe but odds around 1.60ish seemed pretty good for a fighter I think is better everywhere on paper.
