Actually some smaller downfall already happened so to my opinion that was opportunity for making money. It was a temporary correction and the price will grow again in the future. Such situations is hard to predict when or why exactly they will happen but they represent opportunity that any good trader shouldn't mis.
its time for trader and whales taking profits after they buying alot since bitcoin on low price.i see big correction will happen to bitcoin and altcoin now,but don't worry about it just a way to take a breath and collect more power to rise again.
