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.
Lightning networks are going to be deployed pretty soon, so scaling issue won't be so pressing anymore. But I don't agree with your assessment overall: scaling issues don't really affect Bitcoin price growth.
