What would happen when 21 million bitcoins come into existence?

The price will go to the moon, as it always does after each halving.

When we've got 21 million coins the block reward would be tiny as hell. We need high BTC prices to incentivise miners.

When 21 million bitcoins come into existence maybe we will not be alive, but a good percentage of them will be lost and the rest will be held by few people like it is today and a percentage to others.

Bitcoin is a currency, so I think it will no be owned by very few people. People will use it to buy things.

It would need to be a pretty big fee each time a transaction is sent and we would also need to have mass adoption at this point to keep miners mining otherwise i think bitcoin will die a lonely death.
