Countries that recognize Bitcoin include Germany, Japan, Canada, Malta, Estonia, Switzerland, Belarus and Australia. Bitcoin has been controversial in various countries since its birth. Some countries think that its decentralization makes digital currency more hidden, so it is safe and reliable to trade. However, some countries think that Bitcoin is a virtual digital currency and cannot really become legal tender.

First, how to invest in Bitcoin

1. Buy at a bitcoin exchange: Investors should choose a safe and secure bitcoin exchange before investing. Like domestic investors, their preferred platform is OKEX. Investors can choose to buy the desired currency after determining the trading platform and completing the registration and other related information;

2. Purchase through foreign platforms: Investors can also purchase bitcoin on foreign P2P platforms. This kind of foreign platform is more like a middleman, which specializes in bitcoin as a daily consumer product for transactions between investors;

3. Other ways to buy: Investors can also buy Bitcoin through foreign e-wallets. Users only need to register an account, bind a bank card, and have enough funds to conduct bitcoin transactions.

Second, Bitcoin is a virtual cryptocurrency based on decentralization, adopting peer-to-peer network and * * * initiative _ open source code, and taking blockchain as the underlying technology. It was put forward by Satoshi Nakamoto in 2008 and was born in 2009. The biggest difference from other virtual currencies is that its total quantity is very limited and scarce.

Unlike all currencies, Bitcoin is not issued by a specific monetary institution, but is calculated and generated according to a specific algorithm. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transaction behaviors, and uses cryptography design to ensure the security of all links in currency circulation.

Third, the purchase method

Users can buy bitcoin, and at the same time, they can use computers to perform large-scale operations according to algorithms to "mine" bitcoin. When users "mine" bitcoin, they only need to search for 64-digit numbers with their computers. Then they can compete with other gold diggers by repeatedly solving puzzles to provide the needed numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, they will get 25 bitcoins.

Because the Bitcoin system adopts decentralized programming, only 25 bitcoins can be obtained every 10 minute, and by 2 140, the upper limit of bitcoins in circulation will reach 210 million. In other words, the bitcoin system can be self-sufficient, resist inflation through coding and prevent others from destroying these codes.
