# Holder Tiers

Why hold multiple MBB? It’s simple! More Babies = More Benefits. 

At MBB, there are 2 main roles, **Monkey Baby Holders (1+)**, and **Bus Drivers (15+)**.

An overview can be seen below:\

Both holders of 5+ MBB NFTs and Bus Drivers have access to MBB Fireside Chats. These informal talks are held with influential members of the Solana Community on a regular basis, allowing you to gain intimate insights into new, emerging and successful projects directly from their founders.

The Bus Driver chats are available exclusively to those who hold the required amount of MBBs. These exclusive chats provide you with the opportunity to engage with a tighter-knit group, while still being part of the broader community. Additionally, there are various opportunities only available to members of these tiers.
