Some people just buy bitcoins as an investment, hoping that they’ll go up in value. Coinbase is a leading exchange, along with Bitstamp and Bitfinex.

Terms under which this service is provided to you. You may have heard the term hash or SHA-256 , but what do they actually mean ? In order to decide which block of transactions will be entered next to the blockchain some sort of contest is held between the miners.
Imagine that you are a Bitcoin miner, and each time you want to enter your block into the blockchain and get a reward you would be given a combination lock and would need to guess the combination in order to enter your block. So the more computing power you have the faster you’d guess the combination. Since the Bitcoin network wants to keep the time between blocks created in the blockchain constant, as more miners or computing power are added to the network it will become harder to guess the combination. Just imagine that as more and more people try to guess the combination you will be given locks with more possible combinations. A hash is just a method used to guess the combination for the lock.
