Where to invest in Helium?

As an investor seeking opportunities in the rapidly evolving cryptocurrency and blockchain industry, I'm particularly intrigued by the potential of Helium, a decentralized wireless network that aims to revolutionize IoT connectivity. But with so many options out there, I'm wondering: Where is the best place to invest in Helium? Should I be looking at purchasing HNT tokens directly on a cryptocurrency exchange? Or are there other avenues, such as investing in projects building on the Helium network or participating in Helium's staking and mining incentives? Additionally, what factors should I consider in making my investment decision, such as the current market conditions, Helium's roadmap, and the overall health of the Helium community? I'd appreciate any insights or advice on how to navigate this potentially lucrative but also complex landscape.
