Is it safe to register bitcoin with ID card
1. Crowdsourcing is an app software that helps each other to realize mutual economic assistance among members
As a legalized platform, general information will not be disclosed to other companies.3. It is not dangerous to register with your ID card. You just bind your ID card, not your bank card, so there will be no property loss
Strictly speaking, it will not cause any danger5. If you feel that there is danger, it is recommended that you cancel the real name registration. This is the safest solution
Mine hoist is mainly composed of motor, recer, drum (or friction wheel), braking system, depth indication system, speed measuring and speed limiting system and control system, etc., which is driven by AC or DC motor. According to the working principle of lifting wire rope, it is divided into winding mine hoist and friction mine hoist. There are two kinds of winding type mine hoist: single drum and double drum. The winding mode of wire rope on the drum is similar to that of general winch. Most of the single cylinder has only one wire rope, which is connected to a container. Each drum of the double drum is equipped with a steel wire rope to connect two containers. During operation, one container rises and the other drops. Winding mine hoists are mostly used in mines with annual output less than 1.2 million tons and well depth less than 400 meters. The lifting rope of friction type mine hoist is hung on the friction wheel, and the friction force with the friction wheel liner is used to make the container rise. Two ends of the lifting rope are respectively connected with a container, or one end is connected with a container, and the other end is connected with a counterweight. According to the layout, friction mine hoist can be divided into tower friction mine hoist (the machine room is set on the top tower of shaft) and floor friction mine hoist (the machine room is directly set on the ground). According to the number of lifting rope, it can be divided into single rope friction mine hoist and multi rope friction mine hoist. The advantages of the latter are: smaller wire rope and smaller diameter friction wheel can be used, so that the size of the unit is small and easy to manufacture; It has the advantages of high speed, high promotion ability and good safety. This kind of hoist is mostly used in shafts with annual output of more than 1.2 million tons and well depth of less than 2100 meters
