$DEPE

What happens at the end of the bonding curve? Is it locked and we move to a liquidity pool? How does that work?

not sure if u are familiar with pump.fun but at the end of the bonding curve it converts into a liquidity pool. 
eventually you can mint out all the tokens right? what happens then? cause if there is nothing after then it puts a ceiling on price right?

There typically isn't an end to bonding curves, price just gets incrementally more expensive as you move up the curve. Purchases increase the price and proceeds are locked in the pool, redemptions removes funds from the pool and decrements the price.

Unless DEPE is doing something unique...
