Meanwhile，there was also a lot of worthless air-coin happened in many developing country. Most of these cryptocurrency are swindlers. And their characteristics are similar as below:\n1. Registration:  If you want to registe, you must have a invitation code.  This invitation code bases on pyramid selling system. It  encourages the early entrant seek more and more uninformed people. The more people, the greater the possibility of deception.\n2. Controlled price: the price of coin is controlled by charlatan. It shows the people a more optimistic future and not a risky investment. The coin price has been rising since its birthday even during collapse preiod.\n3. Community: The  charlatan established many social networking platforms to gather many uninformed people. People are motivated by  the rising price and begin to seek more  efficient method.\n4. Mills:  The charlatan has developed some kind mills. In fact, their mills are time-counter of possession. But if you want this counter, you must purchase the lager mills. When you express purchase will, there will be some enthusiastic people to promopt mills to you at once.\n5. Cut off:  when you get more coin, you want to sell them.  At this moment, you will find that everyone on trading list will refuses you invariably. And after several attempts, you will be cut off to load the website someday. And now,the game is over.\n6. The same owner:  tracking IP of these websit can help you  distinguish these fraud air-coin in a way because of the same owner.\n![QQ图片20180215165512.jpg](https://steemitimages.com/DQmNWBBzmca6Jaygb2jacFJbcALt8KSCpakDxHcYCfi1AzH/QQ%E5%9B%BE%E7%89%8720180215165512.jpg)![QQ图片20180215165526.jpg](https://steemitimages.com/DQmaiwN3HpWA8Sr2YmUFSMmk4W4MXeHwzrC2v9sksx4MFag/QQ%E5%9B%BE%E7%89%8720180215165526.jpg)",

      "body": "I am a math teacher. I meet a lot of students who have difficulties in learning mathematics. According to my observation, most of trouble  is caused by the lack of scientific and effective training in the pre- arithmetic phase before 7-years-old.![timg.jpg](https://steemitimages.com/DQmeTiax5B3Z47UT8mwHM6kdUN5E9Arii6h6Ldc8iG8LAUn/timg.jpg)\nIn addition to the conventional method, Is there another  method to help these little children traning their math abilities such as: counting, classify, corresponding?\nWhen I were contact with Blockchain, I knew it is a data base which can fill in data decentralizedly. So I think  if we make a chain which can record the baby’s train behaviour started from 4-years-old to 7-years-old.  These unchangeable data will be very improtant role when the boys and gilrs met troubles in learning Math: the teacher could find the pupil’s defectness in their early training of basic skill in Math and he would know how to make remediations.\nSo I think blockchain can be uesd in  Math Education. How do you think?\n![tim1g.jpg](https://steemitimages.com/DQmesKztqzYT6XFsCGSLT7NTphGMAcyRgAnF9wSUBkaFARm/tim1g.jpg)",

      "body": "The earth has been becoming warmer and warmer according to the temperature monitor records in recent decades. But the stmophere temperature does not support this view recently.\nAccording to the law of nature, the sunny and wet air from western Pacific would flood into every corner of  JiangNan regin (JiangSu, ZheJiang,AnHui province) in China at this time, but this regin is covered with heavy snow now. Why does this happen?\n![QQ图片20180125142347.jpg](https://steemitimages.com/DQmapWsSiiVkAcxTQwzNwxink6bx9XopovNVCtxQW9bxmGP/QQ%E5%9B%BE%E7%89%8720180125142347.jpg)\nFor simplicity, we only consider the North Earth.\nAs we know, the broiling sunlight heats the sea water at the ocean surface near the equator. The warmed sea water flows from the equator to the North Pole and brings the heat to NorthEarth. This is why we can live in mid and high latitudes.\n![equator.jpg](https://steemitimages.com/DQmQdMcTd8soo5Y8J26rNj2t4vo13QKNAHgasTjEPFqcske/equator.jpg)\n        \n        Warmer water is colded into ice by iceberg of North equator. The salt is separated into water and  make the water become high density. In the vertical direction, more and more heavier water gather and become a vertical flow to mid deep or even bottom of the sea.  It is easy to understand that a cold flow to equator  will appear to form a closed loop water transptation. This water transptation keeps balance for tens of thousands of years\n  ![iceberg.jpg](https://steemitimages.com/DQmT6k6oiiDXgeasbDg1Jfkz38khCnMn7xrFFCbvCUpYPFc/iceberg.jpg)\n     It is unfortunately this balance was destoried and the vertical flow has become weaker and weaker because of warmer earth and vanishing iceberg. During the past winter,  the sea water has not bright in enough heat from equator and bright out corresponding cold water. The equator has become colder and colder. At last, the cold air charged into high and mid latitudes and met the wet air from east Pacific.\n    ![QQ图片20180125142406.jpg](https://steemitimages.com/DQmXGSRNxH3ZZ5KCMHdsf9CMuToYMQpWWyJ1xUSAT4rB85N/QQ%E5%9B%BE%E7%89%8720180125142406.jpg)",
