How Bitcoin works?
Once you own bitcoins, they possess value and trade just as if they were nuggets of gold in your pocket. You can use your bitcoins to purchase goods and services online, or you can tuck them away and hope that their value increases over the year ..
Bitcoins can be used to buy merchandise anonymously. In addition, international payments are easy and cheap because bitcoins are not tied to any country or subject to regulation. Small businesses may like them because there are no credit card fees. Some people just buy bitcoins as an investment, hoping that they’ll go up in value.
Buy on an Exchange
Many marketplaces called “bitcoin exchanges” allow people to buy or sell bitcoins using different currencies. Coinbase is a leading exchange, along with Bitstamp and Bitfinex. But security can be a concern: bitcoins worth tens of millions of dollars were stolen from Bitfinex when it was hacked in 2016.
People compete to “mine” bitcoins using computers to solve complex math puzzles. This is how bitcoins are created. Currently, a winner is rewarded with 12.5 bitcoins roughly every 10 minutes.
Future in question
No one knows what will become of bitcoin. It is mostly unregulated, but some countries like Japan, China and Australia have begun weighing regulations. Governments are concerned about taxation and their lack of control over the currency.
