In the final analysis, whether a project can make money or not most of the time does not depend on the model, but on whether there is a good project team, whether there is a large amount of funds in the early stage and whether it is willing to accept the initial selling pressure of the market. Those with a big pattern will take over, while those with a small pattern will run directly. This is the most difficult point to consider in the speculation process.
