Characteristics of digital money market
digital currency is a kind of legal tender, which must be issued by the central bank. Both digital gold coin and cryptocurrency belong to digital currency, which is not a network virtual currency, because it is not limited to virtual space, but is often used for real goods and services transactions, such as bitcoin, Wright coin, bitstock, etc. at present, there are thousands of digital currencies issued around the world

1. Impact on financial infrastructure
the decentralized mechanism of value exchange based on distributed ledger technology has changed the basic settings of gross and net settlement on which financial market infrastructure depends. The use of distributed ledgers also poses challenges to trading, clearing and settlement, as it promotes the disintermediation of traditional service providers in different markets and infrastructures. These changes may have potential impacts on market infrastructure other than retail payment systems, such as large payment systems, securities settlement systems or trading databases
If digital currency and distributed ledger based technology are widely used, it will bring challenges to the intermediary role of financial system participants, especially banks. As a financial intermediary, banks perform the ties of acting supervisors and supervise borrowers on behalf of depositors. Usually, banks also carry out liquidity and maturity conversion business to realize the financing from depositors to borrowers. If digital currency and distributed ledger are widely used, any subsequent disintermediation may have an impact on savings or credit evaluation mechanismspay attention to risks in investment!
There is a roller coaster in the digital money market, which rises fast and falls fast. Because digital money itself does not have the channel directly connected with the purchase value in real life, so it is only affected by the market supply and demand. In short, most investors think it is valuable, it will be valuable
take bitcoin, which is very popular now, as an example. At this time a year ago, the price of bitcoin should be about $8800. A year later, the price of bitcoin rose to about $50000. Three months ago, the price of bitcoin did not break through $20000. Three months later, the price of bitcoin is now $50000. The price of a while ago rose to $57000, The price rise is completely higher than that of the stocks in the market and that of the normal funds, because it is a virtual currency, it may rise rapidly in a short period of time, but it may also fall rapidly in a short period of time, resulting in a cliff like price fall{ RRRRR}
bitcoin can make a person rich overnight. If you bought bitcoin a year ago or five years ago, the value is far more than doubled. You can realize wealth freedom soon, but now you buy it again, it's not a good time. No one can guarantee that there will be any good news or bad news in the future bitcoin market, If a big investor buys and has good news, his price may exceed $60000, if not, he may fall back to $40000 or even lower, which is quite possible
insert a paper clip or SIM card ejecting tool into the small hole on the SIM card bracket, and then push it inward towards the iPhone to eject the SIM card bracket. Please pay attention to the gap in the corner of the new SIM card. Place the new SIM card in the bottom of the bay. Because of the gap, the SIM card can only be loaded in one direction. Then insert another SIM card into the groove at the top
after the two nano SIM cards are placed, insert the bracket completely into the device according to the direction when removing the bracket. The bracket can only be inserted in one direction
extended information:
we all know that the iPhone's battery life is very flattering, and the battery capacity is always a little less than others. So we should take good care of her when we use it, so that its life can be longer
generally, the life of a battery is between 1.5-2 years. If the battery health value of Apple mobile phone is less than 80%, it is time to replace the battery

Apple battery can be said to be expensive, so normal and healthy use can save you a lot of money
today, I'd like to share with you my experience in maintaining the iPhone Battery.
1. It's the simplest and most important thing. Never use a charger other than the original one. And don't use the iPad charger to charge the iPhone, because the iPad won't be happy
if the charger is not original, the current will be unstable, which will lead to shorter battery life
2. Complete the charge and discharge of the battery once a month (fully charge the battery and then use light), so that the lithium ion can keep active and flowing
3. Whenever the mobile phone prompts to update the system, it is necessary to actively upgrade the system and software version in time. The upgrade of IOS system helps to optimize the battery
4. If you don't use the mobile phone, open and close all background applications (Apple's official optimization suggestion)
5. The best temperature range for Apple mobile phone operation and storage
6. No matter which mobile phone is used, location service is a very power consuming function, which will affect the battery life. Therefore, the location service function should be turned off as far as possible when it is not needed Setting - General - location service
7. In the app store, some applications will use the notification service in the mobile phone to send you new data reminders. These applications relying on push notification will affect the battery life, so we need to disable push notification. And it will not prevent the application from receiving new data.
