If there's a big crash coming then that's a good opportunity for everyone who holds a lot of money to buy items in cheap price
Well if the big crash is coming soon and make bitcoin prices go down, I think this is really becoming a very precise moment to buy many bitcoin before halving occurs
The price go down or up, its always a good thing to hold as much possible bitcoin during the days of halving. Now if some crisis happens we can expect a price to go down as the past to some extent but would surely increase in a short. The present time increase in price is an example for it.
