1995 is the most terrible time to double. Because it was launched on 19921February 28th, it was only open to brokers themselves, and then it was opened to the outside world. Then it reached its peak in 1999 and 1995. In its heyday, there were two risk events, 3 14 and 327 treasury bond futures events, the most striking of which was the 327 event, and the parties concerned are still in custody. So 1995 is the most terrible time to double.
