Bitcoin Forum

We know that only 21 million Bitcoins can be mined in total. What next ???

Nothing.

Miners will be mining for the tx fees.
Users will continue to shop/hold/trade bitcoins as usual.

The downside is than none of us will be still alive to confirm this by the time the last satoshi is mined.

This question pops up at least once a week, i always give the same answer: whenever you have a question about btc, use the google custom search on this forum before opening a new thread => click the magnifying glass at the top right corner, enter your question in the google custom search field, and press "google search".

No more Bitcoins will be created (if we don't count the forks, of course).
Mining and the network will be supported from transaction fees only.
But I highly doubt, that Bitcoin will still be PoW after 15 years.

After mining all the bitcoins of 21 million there is still demand for bitcoins and more user's will be entering the bitcoin market due to high demand the value of bitcoins will still keep on increasing it might surpass above $20000 in the near future. Due to rise in price of bitcoins it attracts more user's every day to the crypto market, and this bitcoin technology is a good commodity of investment or in other words the bitcoin network will help to gain more profits from investments as we can see from the previous years value of bitcoins the value has increased drastically, there is good potential for the bitcoins to increase by ten fold the current value of $8200.

What is going to happen, is transaction fee's are going to explode.

Then the hidden part of code will run, robots will rise and kill all human  :D  ( just a joke, above replies are correct)

Everything will flow smoothly without a hiccup because it will be anticipated because mining rewards are halved approximately every four years, and eventually (long after we are dead) miners will want to process transactions for the fees and not newly mint coins. Supply has never (and will never) been a problem because there are such things as .00000001 of a Bitcoin

maybe the price will raise to Plato but I am only wishing the the fee will decrease since the miner only do a transfer. Let us wait and see what will happen in the future.

Once all 21 million Bitcoins are mined, no more can be created. However, we will still need the miners to do all of the work required for completing and confirming transactions. Instead of the miners getting paid in new Bitcoins and transaction fees, they will be paid solely from transaction fees.

I can imagine that fees will be a little higher at this point but we are talking about 100 years in the future and Bitcoins will be very valuable at that point.

It will fork and make another 21 million...and another....and another

thay will stay tradable and thst's all. there will be no any sense in btc mining.  :-\
