On December 16, news, early cryptocurrency advocate Trace Mayer said during a podcast show that hacking events such as Quadriga CX or Mt. Gox were good for bitcoin prices. Mayer uses Coinbase as an example to explain that Coinbase has 20 million customers. Assuming that each customer has 0.1 Bitcoin, it is equivalent to 2 million Bitcoins. Assuming Coinbase is down and customers lose 2 million bitcoins, this will cause already scarce goods to become scarce. Therefore, according to the logic of supply and demand, this hack may in turn push the price of Bitcoin in the hands of other holders.
