Because blockchain networks are decentralized and open-sourced, anyone can fork a blockchain network to create a new cryptocurrency. Forks can be contentious (a disagreement between users of the network) or planned (an upgrade to make the network better).
“Remember when Bitcoin had its fork and created Bitcoin Cash? People are still fighting about those two blockchains to this day.”
