I heard that miners confirm transactions. If so, how does a proof-of-stake coin confirm if there are no miners? Also, when a coin will hit it's hard cap (21 MIL for BTC), if everyone stopped mining at that time, will the coin die?

Thanks,

There are no miners = there are no confirmations, and nothing will prevent double spends andd other attacks, wether if it happens because internet is shut down, or because no one wants to mine the coin.

And after all the coins are mined, there still will be the transaction fees as reward, and the desire of people to keep bitcoin alive.
