This question already has an answer here:

I've understood for a while that bitcoin mining was a process that required computers to solve increasingly difficult problems in order to mine a block.

It wasn't until now that I realized those "problems" are actually the act of keeping track of all bitcoin transactions, updating the block chain.

Before this, I thought every bitcoin client on earth did that work to keep trackof the block chain together.

With this new understanding, I have to ask:

When all bitcoins have been mined, and there is no more reward for this computation by butcoin miners to update/keep track of the block chain, why would people continue to spend the resources to accomplish that task?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • Perhaps a dynamic bitcoin transaction fee based not on the size of a transaction but on the value of the bc will be used to continue to reward miners for their hardware's work in keeping the bc network going? – Jonathan Apr 19 '15 at 17:05
  • There are some transactions in one block. Miner will collect all transaction fee as reward. – moshaholo Apr 20 '15 at 14:28
