Is it worth putting $100 in Ethereum?

I'm relatively new to the world of cryptocurrency and I'm considering making my first investment. I've heard a lot about Ethereum and its potential for growth, but I'm still a bit uncertain. Given the risks and volatility associated with crypto, is it really worth putting $100 in Ethereum? What kind of returns can I expect, and how long should I be prepared to wait before seeing any significant gains? Also, are there any specific strategies or tips you would recommend for a beginner like me? Thank you for your help!
