There are different types of cryptocurrency exchange scripts available for crypto trading such as centralized, decentralized, peer-to-peer, white label, and hybrid exchanges. Centralized exchanges are operated by a single entity while decentralized exchanges operate on a blockchain network. Peer-to-peer exchanges facilitate direct transactions between buyers and sellers. White label exchanges allow users to customize their trading platform, while hybrid exchanges combine the features of centralized and decentralized exchanges. Each type has its own advantages and disadvantages, and the choice of exchange script depends on the specific needs and preferences of the trader.
