Will it benefit the bitcoin miner after all the bitcoins are mined?
You should not expect to be rich with Bitcoin or with the emergence of other latest technologies. The most important thing to be careful of everything that sounds too good and amazing to be true or violate the basic principles of economics.
Bitcoin is a growing innovation and business opportunity that also has risks. There is no guarantee that Bitcoin will continue to grow even though it has grown so rapidly to date. In Investing time and resources on everything related to Bitcoin requires entrepreneurial skills. There are many ways to make money with Bitcoin like mining, speculation or running a new business. For all methods are competitive and there is no guarantee of profit. It all depends on each individual to make an evaluation of the costs and risks that may arise in any project.
And bitcoins are virtual like credit cards and online banking networks that we use every day. Bitcoin can be used for online payment in real stores as well as using conventional money. Bitcoin can also be exchanged for material forms such as Denarium coins, but mobile phone payments are usually easier. Bitcoin balances are stored on a large distribution network and these balance values can not be cheated or altered by anyone. In other words, Bitcoin users have exclusive control over their money and bitcoin can not be lost simply because it is virtual.
Only a fraction of all the bitcoins that have been issued today are sold in the exchange market. The Bitcoin market is competitive, meaning bitcoin prices will rise or fall depending on demand and supply. Moreover, the new bitcoin will continue to be published in the coming decades. Therefore even the most ambitious buyers will not be able to buy all the bitcoins that are present today. However, these circumstances do not indicate that the market is not susceptible to price manipulation and still does not require substantial amounts of money to drive up or down market prices, so Bitcoin is still a relatively volatile asset so far.
