In fact, for companies preparing to go public, the state control is still quite strict! First of all, enterprises must have the corresponding qualifications, and they must sign up for listing counseling brokers! If your project can't see this, it's not credible. In order to avoid this, many companies will go public elsewhere under the banner of confusing investors!
Secondly, it depends on whether the enterprise has signed a formal paper contract with legal benefits signed by the legal person and sealed by the company! There are many terms in it, such as how long it is agreed to go public (1-4 years, usually two years). (Two years later, the enterprise will be listed on the New Third Board, and your principal can be increased by 3- 10 times according to the project situation. If you continue to go to the main board, it is expected to be more than several times. If it is not listed within the specified time, the enterprise must unconditionally buy back all the shares of its customers. In other words, how much you invested at the beginning must be returned in full within the time stipulated in the contract, and you will be given corresponding interest every year, generally above 8% and below 15%. If you don't go public, you will get much higher interest than the bank interest, and there will be no loss, which really avoids the risk. )
There are two important points, that is, 1 see if he gave you a stock certificate instead of a string of numbers on the website! If you have a lot of money, does the enterprise assist you to go to the industrial and commercial bureau to go through the shareholder procedures? You can see the names of your shareholders on the website of the Industrial and Commercial Bureau or Tian Yue. )
These are the most basic, if not, it will be very dangerous. As far as I know, none of the enterprises you mentioned!
