Bitcoin is Ethereum Code Review made through a process called mining. Just like paper money is made through printing, and gold is mined from the ground, Bitcoin is created by 'mining'. Mining involves solving of complex mathematical problems regarding blocks using computers and adding them to a public ledger. When it began, a simple CPU (like that in your home computer) was all one needed to mine, however, the level of difficulty has increased significantly and now you will need specialised hardware, including high end Graphics Processing Unit (GPUs), to extract Bitcoin. How do I invest First, you have to open an account with a trading platform and create a wallet; you can find some examples by searching Google for 'Bitcoin trading platform' - they generally have names involving 'coin', or 'market'. After joining one of these platforms, you click on the assets, and then click on crypto to choose your desired currencies. There are a lot of indicators on every platform that are quite important, and you should be sure to observe them before investing. Simply buy and hold While mining is the surest and, in a way, simplest way to earn Bitcoin, there is too much hustle involved, and the cost of electricity and specialised computer hardware makes it inaccessible to most of us. To avoid all this, make it easy for yourself, directly input the amount you want from your bank and click "buy', then sit back and watch as your investment increases according to the price change. This is called exchanging and takes place on many exchanges platforms available today, with the ability to trade between many different fiat currencies (USD, AUD, GBP, etc) and different crypto coins (Bitcoin, Ethereum, Litecoin, etc). If you are familiar with stocks, bonds, or Forex exchanges, then you will understand crypto-trading easily. There are Bitcoin brokers like e-social trading, FXTM markets.com, and many others that you can choose from. The platforms provide you with Bitcoin-fiat or fiat-Bitcoin currency pairs, example BTC-USD means trading Bitcoins for U.S. Dollars. Keep your eyes on the price changes to find the perfect pair according to price changes; the platforms provide price among other indicators to give you proper trading tips. Bitcoin as Shares There are also organisations set up to allow you to buy shares in companies that invest in Bitcoin - these companies do the back and forth trading, and you just invest in them, and wait for your monthly benefits. These companies simply pool digital money from different investors and invest on their behalf.
