It's very difficult to say when will be a time for buying. News background can be temporary and have controlled whale market. The better waiting a stability growth and go than spend on the bottom.
The currency market is very difficult to predict, for now the bitcoin price range is 6,000 USD to 7,000 USD. But for the future, full of uncertainty. Can rise higher, or go down in price. If I think the current price has begun to be corrected so the rise is not too high, down slightly.
