How can I buy ARB?

Hello there, I'm interested in purchasing ARB cryptocurrency but I'm not sure where to start. Could you please guide me through the process? What platforms or exchanges can I use to buy ARB? Are there any specific steps I need to follow? Also, is there anything I should be aware of before making my purchase, such as fees, security measures, or potential risks? I'm eager to get started but want to make sure I'm making an informed decision. Thank you in advance for your help!
