How to get ONG?

Could you please elaborate on the process of acquiring ONG tokens? I'm particularly interested in understanding the various methods available for acquiring them, including but not limited to exchanges, airdrops, staking, or other avenues. Additionally, could you provide some insight into the potential risks and considerations that one should be aware of when acquiring ONG tokens? Furthermore, are there any specific requirements or steps that one needs to follow in order to successfully acquire and store ONG tokens securely?
