What is BTR for today's TGE?

It is the token of #Bitlayer : Simply put, BTR is a token that 'assists' Bitcoin. Bitcoin is well-known; it is secure, but its functionality is relatively simple and not suitable for complex applications.

Bitlayer is like having a 'secondary runway' next to Bitcoin, and BTR is the 'currency' on this secondary runway. It allows Bitcoin to become more flexible, supporting new things like decentralized finance and various mini-programs, without affecting the security of Bitcoin itself. ​@BitlayerLabs
