Crash its price? Well this is just a normal thing and nothing to be surprised of. If there are sellers on a certain coin then prices would normally react on that which would go down. If theres a crash and prices are too low then its the best time to buy or accumulate cheaper coins. Its somehow risky to do since we wont know on when it would pump again. Just take a look on XMR now,its pumping as of now later on we would see bears again when they decide to sell.
