Which chain is Big time on?

Excuse me, could you please clarify what you mean by "Which chain is Big Time on?" Are you referring to a specific cryptocurrency project or platform named "Big Time" and wondering which blockchain network it's built on? Or is it a more general inquiry about which blockchain network is currently experiencing significant growth or popularity in the cryptocurrency space? If it's the latter, it's worth noting that the popularity of blockchain networks can vary greatly depending on factors such as scalability, security, adoption, and use cases. Some popular blockchain networks currently include Bitcoin, Ethereum, Binance Smart Chain, Solana, and Cardano, among others. However, it's important to keep in mind that the cryptocurrency market is highly volatile and subject to rapid changes, so the popularity of any given blockchain network can shift over time.
