It seems that what you suggest is very reasonable, because if many believe in bitcoin and start buying it, the price will definitely go up again and now is the right time to buy it, because the price of bitcoin is now quite low.
It's hard to convince people as they already seen what happen previously, though we are not sure what fate will bring if ever there's people who's willing to take the risk buying and holding their coins, aside from the whales who's always waiting for the perfect timing collecting their profits whatever the market goes.
