Anyone can know how I can find, earn, bitcoin by confirming transaction? Someone told me that I can earn bitcoin/money by just confirming transaction. Is that true?
Yes, in order to confirm transactions for the network you need to find ("mine") a block. The current reward for finding a block is 25 BTC (plus some fees). Soon the reward will be lowered to 12.5 BTC (the event is called "the halfening"). In order to mine you need a machine that is capable of calculating SHA-256(SHA-256(some data here)) quickly and efficiently. In the distant past this was done with regular computers, followed by a period where graphics cards where used. Now there is specialized hardware (called ASIC for application specific integrated circuit) which requires you to invest a significant amount of money into hardware before you can see small returns. Unless you are able to make a large investment dont bother with mining, cloud mining is often a front for a ponzi or not profitable, mining with the hardware you have (e.g. a regular PC) is not profitable because its power consumption is too high. Mining with old ASICs isnt worth it either unless you have access to very cheap electricity.
