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.
There is nothing predictable in this market. The temporary correction today has caused many traders to have a huge loss and surely the next big correction will happen in the next few days. I think the market has increased in the past 3 weeks and now is the time people to face their financial difficulties during this time. If you are a smart investor then you can sell at a good price yesterday
