Tencent science and Technology News reported in December 14th, according to foreign media reports, with bitcoin prices reaching a record high again on Tuesday, Coinbase, the largest trading platform of bitcoin, finally collapsed under the heavy traffic pressure, which made about 10000000 users unable to withdraw their funds at that time. Meanwhile, another large bitcoin trading platform, Bitfinex, also said it had been attacked by a large-scale DDoS. This means that the server of the platform was deliberately placed in the garbage network request, and the website was temporarily shut down, and the service was terminated. These two examples show that the current bitcoin trading market is still in an immature and unstable condition, there are millions of investors into, let each platform be caught off guard unable to cope with the sudden change, and this will inevitably make investors worried. On this special day in December 7th, the price of bitcoin on the Coinbase trading platform was less than an hour.
