The minimum capital required to start a basic, ready to market cryptocurrency exchange ranges from $6,000 to $8,000. This would cover the initial software development and basic infrastructure costs needed to launch a simple yet functional exchange. The software can be built on open source code like GitHub to reduce development costs. Basic infrastructure would include server hosting, SSL certificates for security, and setting up cryptocurrency wallets. This would allow you to launch a basic exchange to market with core trading features.

For a more advanced exchange platform with more complex features, the costs start from around $10,000. This would include developing a custom platform with advanced trading engines, margin trading, payment gateways, mobile apps, liquidity integrations and more. More robust security and infrastructure would also be needed.

Overall, the capital required depends on the features and functionality you want in your exchange. But with an experienced development partner like Bitdeal, it's possible to launch a quality exchange platform within your budget.
