How to purchase CRO?

I'm quite curious about cryptocurrency investing, especially the CRO token. Could you possibly elaborate on the process of purchasing CRO? I'm not entirely sure where to start or what steps I should follow. Is there a specific platform or exchange that's recommended for buying CRO? Also, are there any safety measures I should take into account while making such transactions? Would you mind guiding me through this entire process from start to finish? It would be greatly appreciated.
