That is the time to buy more bitcoin. That is what i am hoping for the past month. But it won't gonna happen though. Bitcoin will go down but just a little then it will go up double.
The next major spike may occur after 6-7 months, when NASDAQ will list the Bitcoin futures. Until then, the prices are either going to remain at $15K-16K levels, or going to slide further. I would advice you to wait for a few more days, so that the trend is clear. As long as the scaling issue persists, the price is not going to climb upwards.
