how much does a bitcoin worth?
Some say:“Worthless. It’s just a Ponzi scheme.”
Some hail:“Priceless! It’s the future of money.”
A Chinese economist Ou Chengxiao,  often nicknamed”Ou Guru” said yesterday "The price of bitcoin is 1000 times overvalued". He believed that the value of currency is decided by its scale of circulation, or adoption. But now the lack of businesses that accept the digital currency as payment has been holding bitcoin back from wider adoption. not so many people are buying things with btc.
 i am a little confused why he is so sure bitcoin price is 1000 times overvalued. why not 100? 10? why exactly 1000? Do you agree with him?
