What are the rates of onus?

Excuse me, could you please clarify what you mean by "rates of onus"? Are you referring to the fees or charges associated with cryptocurrency transactions or investments? If so, it's important to note that these rates can vary widely depending on the specific cryptocurrency, the exchange or platform being used, and the type of transaction being conducted. Some exchanges may charge a flat fee per transaction, while others may use a percentage-based fee structure. Additionally, there may be other costs to consider, such as network fees or withdrawal fees. It's always a good idea to carefully research and compare the fees and charges associated with different options before making a decision.
