Digital currency, which is more mainstream, can invest appropriately, taking into account both the source and the provenance, which is risky, and the investment needs to be cautious.

Digital currency Stock Exchange is a trading place developed by using cryptocurrencies such as Bitcoin. In the early days, it was only an institution that provided transaction matching services for cryptocurrency holders. Since then, with the global expansion of the cryptocurrency market, a special exchange has finally formed, and its service scope has expanded from cryptocurrency to digital assets, providing various derivative transactions such as contracts, futures and over-the-counter transactions. Nowadays, the exchange not only undertakes the functions of narrow exchange, that is, it provides trading circulation and price discovery, but also provides a series of financial services like banking, brokerage, clearing and settlement. It can be said that the position of the exchange in the encryption digital currency industry is just like that of the super giant financial holding group company in the traditional financial system. Although it is not "too big to fail", any trouble will have a huge and far-reaching impact on the whole industry.

If the mining machine is the first printing machine in the blockchain world, then the exchange is the second printing machine in the blockchain world. Different from the big miners who make a fortune in the depths of the mountains, the exchange makes money at an amazing speed-the fees of each digital currency, the trading commissions of all users, the withdrawal fees and other income, coupled with the rising price of digital currency published by the exchange itself, make the exchange look like a "nuclear printing machine". From numbers to currencies, digital currency Stock Exchange is the only way for Token to become coins, the most intuitive place to show the technical value of blockchain, the magic golden finger to turn the stone into gold, the centralized place to realize the goal of decentralization of blockchain, and the capital to realize greed and ideals.
