How much theta is good?

Could you please elaborate on the question, "How much theta is good?"? Are you inquiring about an appropriate amount of theta tokens to invest in, or are you asking about the ideal theta level for a specific technological or financial application? If it's the former, could you provide some context, such as your risk tolerance, investment goals, or current portfolio composition? If it's the latter, could you specify the context in which theta is being discussed, such as in blockchain consensus mechanisms or within a particular financial model? Understanding the specific context would help me provide a more accurate and useful response.
