How do I check my CTC?

Could you elaborate on the process of checking one's CTC, or cryptocurrency Trading Capacity? I'm curious about the specific steps one would need to take in order to accurately assess their ability to engage in cryptocurrency trades. Would it involve analyzing past trades, evaluating current market conditions, or is there a specific tool or calculator that can assist in this assessment? I'm looking for a comprehensive understanding of how to ensure I'm making informed decisions when engaging in cryptocurrency trading.
