The official account of bitcoin old cat

1. There is no such thing as "global digital currency online" in the mainstream currency circle. There is no relationship between bitcoin and DGC. Bitcoin, Ruitai and Laite are all open source digital cryptocurrencies, which have been widely recognized in the market. The Chinese name of DGC is sharecoin, which often carries out some false propaganda. Bitcoin is just a tool to be used.

2. I haven't heard of the official account of WeChat, but I don't know what's known in the currency circle.
to learn about bitcoin, you can go to bitcoin home, bitcoin.com and other information websites. DGC's Chinese name is shared currency, which is a marketing currency. It is different from bitcoin, and can't be compared with Ruitai and Laite.

3. You can refer to the whale exchange. It is a decentralized exchange with good user experience and reputation, and supports the whole platform coverage. Whether you use PC or mobile app, you can complete the transaction, which is simple and easy to use.

4. Pishon is a very large, real blockchain smart contract DAPP. All program rules are deployed on the (wave field) public chain. People can't tamper with it. Many people agree

Stars emit light and heat by fusing lighter elements into heavier ones. All kinds of nuclear fusion reactions take place in stars all the time, the most important of which is the reaction of hydrogen fusion to helium

in stars with different mass, the reaction path of hydrogen fusion to helium is also different. In smaller stars, the fusion reaction of hydrogen nuclei takes place through proton proton chain reaction. The process is shown in the figure below

‍

whether it is to split the iron core (fission), or to continue to increase the weight of the iron core (fusion), we need to increase the energy of the iron core. Inside a star, however, there's not enough energy. In this way, the energy generation of the star will stop, and the radiation pressure used to resist gravity will disappear. The star will continue to contract, and the speed of contraction will be faster and faster. Finally, the speed of external matter falling to the iron dominated stellar core will exceed 100000 km / s, but when it reaches the iron core, it will hit an extremely hard "wall", and the speed will instantly drop to zero. The huge kinetic energy will be instantly converted into heat energy, heating the iron core to billions of degrees. The outer layer of the iron core will explode at a very high temperature, exploding the falling material in the outer layer. This process is called "core catastrophe". This is a supernova explosion

at the same time of explosion, under the action of huge energy, a part of iron in the outer layer of iron core will absorb energy and form elements heavier than iron, from 27 element cobalt to 92 element uranium. The iron inside the iron core will press the electrons outside the iron nucleus into the nucleus under the pressure of implosion, and combine with the protons in the nucleus to proce neutrons. All the iron inside is converted into neutrons. When the outer shell is blasted and dissipated into space, the center of the star is exposed and becomes a neutron star with huge mass and small scale

after the stellar matter from hydrogen to uranium dissipates into space, it will mix with the original interstellar matter in space to form interstellar cloud, and form new stars and planets around stars under the gravitational disturbance. This is how our sun and earth came into being. That's how everything on earth except hydrogen and helium comes from

This is the case with nuclear fusion reactions on stars

we are all the ashes of a supernova that erupted billions of years ago

6. Of course, the unique contract transaction on okex is not available in fire coin and coin. It's very easy to use. I use okex.

7. Official account is official account. Official account is not available. If you want to know if a public number exists or whether a company has a public number, can you query through WeChat users? Step up: open the WeChat user page, click the plus sign on the top right-hand corner of WeChat, select the search type public number, enter the name company or related keywords you want to search for the official account, click the search results. Find official account official account of official account official based on the results of the survey, and notice whether the main information of public number is whether it is reliable or not. If the main body is OK and the official account has been certified by V, and the relevant content information is also found in the public number, the public number is the target public number. Click follow to follow all the public contents.

8. Go to the clinic

to put it simply, if you feel uncomfortable, go to the clinic and have a targeted examination. If there is no discomfort, just routine physical examination, go to the physical examination center

if you only want to check your lung, it's better to go to the clinic.
