- I don't think it is about September. In September, 2017 Bitcoin was rising speedly.
- It may related with BAKKT. But I am not sure BAKKT can affect BTC's price this much.
The reason why bitcoin crashed was not that it experienced speedily surge in price in the year 2017 nor was this month a bad month but the current crash was the market correction that usually happens before bitcoin halving.
Bakkt was not implemented to create surge in the price of the market but security and assurance for investors.[/list]
