Twitter's views can be divided into two categories, seemingly the same but fundamentally opposite: One type is to be a banker, investor, or mouse warehouse, but pretend to make a secondary purchase and firmly buy. This type of product often boosts morale when it falls, boasts when it rises, gains fame before, kills pigs behind, and even boosts morale during the final harvest. One type is to have a positive outlook on oneself, buy and share opinions. These people often feel like they are bullish when they rise, but they also become foolish when they fall. The advantage is that the second type will continue to strengthen.
