Do you really think Bitcoin price is going to crash after Block reward halving?
If anything and judging by past performance when the halvening happened, all it does is increase the supply... as expected. The supply shrinks, the demand stays the same (and normally keeps increasing with time) it can only lead to one thing = an higher price.
If we keep making good progress, the halvening pump will happen while the current uptrend is still going on. I think we will reach a point where we just see lateral growth with some up and downs but the all time graph will look like Berkshire Hattaway class A. Bitcoin is a super asset of unique qualities anyway.
