Identification of virtual currency
the other is the private + raised currency which has not been listed in the secondary market and is currently in the ICO stage. This kind of identification will be difficult. First of all, you should be familiar with the white paper of the project. Secondly, let's see what the landing scene is like and what the later plan is.
if you don't understand digital currency, you'd better not touch it. The water of digital currency is very deep. Digital currency is even more chaotic, deception is repeated. If you are interested, you can first learn about the crowdfunding project token on coin Ying China platform.
according to the definition of "appearance design", it refers to the new design of proct shape, pattern or their combination, as well as the combination of color, shape and pattern, which is aesthetic and suitable for instrial application

5. Looking at the left and right horizontal and vertical numbers, there are horizontal and vertical numbers in the lower left corner of the front and on the right side of the front, respectively. The horizontal top word and the first two numbers in the lower left corner are red, the last six digits are blue, and all the vertical numbers on the right side are blue
6. Look at the white watermark. The white watermark is located in the area below the horizontal number in the lower left corner of the front, and the clear 100 words can be seen through light observation

According to their current monitoring and mastering situation, the simulation level of counterfeit currency is not high, and it is absolutely not up to the level of using fake money to confuse real money
although the means of making fake RMB are constantly improving, there are still differences compared with real RMB. I can responsibly say that in front of professionals and machines, there is no place to hide the existing counterfeit money
some counterfeit RMB were found, which were imitated by watermark, security line, color changing ink, micro text and other counterfeit technologies. The criminals use the method of directly using light ink to cover the watermark pattern on the back of the fake RMB, and the security bar is not true. These tactics are very crude and clumsy in the eyes of experts, but they are deceptive to ordinary people
