It will still take a very long time for that thing to happen and I guess all of us are dead by that when all the Bitcoin are mined. I also think a lot of possibilities that might occur during that time but it is better to leave it to those people who will reach that special event of the history(crypto history).

Miners will then quit, no more competition thus reducing the hashrate and then we are back to where it begin which we will use our own laptops to (mine) verify the transaction, we revert back to original satoshi intention which a block can be mined by a common equipment (laptop/desktop). Remember the cause leads to booming in hashrate that give birth to special electronic equipments called "mining device" you will realise that once all of these devices disappear (unprofitable) it with cause a shutdown in an industry called "bitcoin mining" but the ecosystem is still there and everyone is in a state of "contributing hashrate" to help running bitcoin or "transaction verification" using their common equipments laptop/pc and phone even in the event that there is no tx fees. As of today I am sure that a huge amount of 24/7 online PCs (considering bitcoin owners only) are wasting their power (low CPU usage 1%-2%) will be helpful by then. Assume that you already know that your tx will be resolving in the next block, will you mind to start up the wallet and join the process and along the way there are other transactions thus other users too!

By the time all the Bitcoins are mined, we can assume that the adoption will increase to such a level that the majority of the world population will be using BTC regularly. So imagine 5 billion people using BTC for their daily financial needs. Let's assume that they'll pay $0.10 per day for using Bitcoin, as the transaction fee. It comes to $500 million per day and around $180 billion per year. I guess that amount is more than enough to sustain the miners.

I dont really get your point, when bitcoin is all mined we can expect better prices because the demand is getting higher day by day and there is a limited supply of it.

How bitcoin will suvive?

It already survived bro.

After the last fraction of bitcoin has been mined, miners will require some other incentive to continue validating new transactions on the blockchain. The general consensus is that this will happen through transaction fees, but whether this will actually create enough revenue for mining to be worth it or not is anyone’s guess.

I think, we will use some of the remaining BTC in each transaction.  not in exchange.  but in some crypto wallets available.  there is no market for BTC.  but BTC is in everyone's crypto wallet.  because eventually BTC and crypto will disappear.  and at the end of our time we will only use gold and silver.

I am curious also about this topic. What in my mind is when the bitcoin will be mined completely, I only thought that it's price will continue to rise as we have reach the maximum limit already.

But I forgot about the miners, whether they are going to continue in supporting bitcoin or not. If they will profit using transaction fess then I am sure that there are still willing to continue but I am sure also that many will stop due to competition and other problems that will occur someday. This is very crucial and deciding moment once it will happen in the future.

Nope. The entire volume will never get in to circulation. Right now somewhere around 2 million and 3 million coins are being considered as "lost" coins and no one has the private key to access these coins. And on top of that, large amount of the coins are not actively traded, as they are being kept in cold storage. If there is increased demand, then the exchange rate will increase. But the volume of the circulating coins is not going to increase.
