#BTC何时反弹？ $BTC There is a person selling villas, making 36,000 calls a year, 28,800 of which are answered, 11,520 will listen to him speak, 4,608 will show interest, 1,843 will come to see, 737 will consider, 294 will have intentions, 117 will negotiate, 47 want to buy, and ultimately, 18 transactions will earn him 2,000,000 yuan. He concluded: every call made earns him 55.55 yuan. Thus, the question he considers is not 'How many people will answer the phone today?'; not 'How many people will listen to him after answering the phone?'; nor 'How many people will come to see after listening to him?'; but rather 'How many calls can I make in a day?' Sales must have this spirit! Accumulated quantitative changes will lead to qualitative changes!
