I think correction is not over yet.
Bitcoin may touch 7600$ region which is great support level.
Then we will see a bounce and bitcoin will surpass it's all time high.Altcoin will follow bitcoin as well.
Did you miss it? Bitcoin already hit 7.500 USD on gdax and went under on other exchanges, check out the candle wicks. This could easily, easily go below 7k and if that level of support breaks who knows where we will stop.
Bitcoin has already been dropping so fast we couldnt say when it will stop for the big correction. Possible for now it will hit below 7k because of more fuds that happening. But, to answer their is no accurate answer for this when would be more time at this current rate. It is better to buy atleast any amount to invest we will not know the market volatility.
