Is there any reason why the btc price is dropping that much today? Are people scared by the hard fork or why is it dropping?
Its just some big whales dumping their holding or cashing out their profit from this short term huge rally, current pump on price was only supported by high speculation over comming hard fork so bigger dump than this one is quite guaranteed after the hard fork.
That pretty much explains it all. The drops in pricing is normal after a huge rally or bull run. The price will spike or peaks then eventually normalize at some point.
