Simple ethereum question – unlimited supply?

Hello there. I tried to post this in the cryptocurrency subreddit but didn't have the required comment karma.

I understand that ethereum has an unlimited supply, unlike bitcoin or cardano, that is created at an ever decreasing rate. However, if the amount of ethereum is always increasing, even with mass adoption, won't it's worth eventually drop as supply outpaces demand? Isn't it more of a sure bet to invest in coins with limited supply?

I'm not knocking ethereum. I think it is an amazing technology and I am excited about ethereum 2.0 and the improvement of smart contracts. I just want to understand how the unlimited cap plays into price when compared to other coins.
