Where can I buy Roco Finance?

I'm interested in purchasing Roco Finance, but I'm not sure where to find it. Could you please guide me on the best platforms or exchanges where I can buy Roco Finance? It would be helpful if you could also mention any important factors I should consider before making a purchase, such as transaction fees, security measures, and the availability of the coin in my region. Additionally, is there any specific information I should know about Roco Finance before investing in it, such as its use cases, development roadmap, or team background?
