How much does a new network cost?

I'm curious about the financial implications of launching a new cryptocurrency network. Could you provide a general estimate of how much it might cost to establish such a network from the ground up? Factors like infrastructure setup, development costs, security measures, and ongoing maintenance would all be considerations. Additionally, is there a range of costs depending on the scale and complexity of the network? Understanding the financial requirements upfront is crucial for planning and budgeting purposes.
