<p>Miners earning = block reward + fees</p>

<p>Miners will continue to get block reward in the next hundred years, but long before the reward "stops", the miners will get most of their earnings from transaction fees, so they will continue to have economic incentive to mine, when the block reward stops.</p>

Aren't the transaction fees much lower than the current payout of 25 bitcoins? I read that mining is not profitably unless you have powerful GPU's so when the reward is gone, I can't imagine the transaction fees alone will be a good incentive.

@styfle they are now, but once the reward stops being high enough, market should adjust itself: miners would stop accepting low-fee transactions.

@Lohoris I read something about higher transaction fees means the block has higher priority. This might require a new question, but how are transaction fees determined?

<p>According to <a href="https://bitcoin.stackexchange.com/q/161/4095">this question</a>, there will only be 21 million bitcoins at most. These coins are being produced logarithmically by <a href="https://bitcoin.stackexchange.com/q/148/4095">mining</a>, so the payout will decrease as time goes by.</p>

<p>When all 21 million bitcoins are in circulation, will there be any reason for mining? Is mining only useful for us "early adopters" or will it be a permanent part of Bitcoin?</p>

@Lohoris Not quite the same question but very helpful. Thanks.

(Asked by: username_0 on 2013-04-13)

According to [this question](https://bitcoin.stackexchange.com/q/161/4095), there will only be 21 million bitcoins at most. These coins are being produced logarithmically by [mining](https://bitcoin.stackexchange.com/q/148/4095), so the payout will decrease as time goes by.

When all 21 million bitcoins are in circulation, will there be any reason for mining? Is mining only useful for us "early adopters" or will it be a permanent part of Bitcoin?
