How to buy RSR?

Hello, I'm a newcomer to the cryptocurrency world and I'm interested in investing in RSR. Could you please guide me through the process of purchasing RSR? I've heard that it has potential for growth, but I'm not sure where to start. Could you explain the steps I need to take, including choosing a reputable exchange, creating an account, funding it, and ultimately placing the buy order? Also, are there any additional factors I should consider, such as transaction fees, wallet security, or market fluctuations? Your advice would be greatly appreciated.
