Yes, anyone with the technical know-how or access to developers can create a cryptocurrency. Costs vary depending on the complexity of the project. If you're forking an existing blockchain like Bitcoin, the cost can be relatively low. However, building a new blockchain from scratch, including development, testing, and marketing, could range from $5,000 to $100,000 or more. Additional expenses include blockchain hosting, transaction fees, security audits, and marketing campaigns. Moreover, launching an ICO or getting listed on exchanges involves further financial commitments.
