My friend told me few days ago:"Bitcoin would go down to ~7K, and should find support later and then go into real bull run starting at 2018Q3 "
On what exact date your friend told you that? Does your friend have some insider or signal that he's getting from these whales? I also saw small quotation chart that bitcoin would go down to $7,500 and it's likely going to happen but after those down charts it will also up so your friends speculation and the chart I've seen from somewhere looks plausible. I'm starting to believe those charts that are spread online before, I don't believe those as I'm a long term holder and even the price goes up and down I'm looking at future gains.
