Some of the 15BTC investors are showing weak hands and selling at 1300 sat

They can't wait for surprise announcements.
Some will sell 7 to 10 BTC to get investment back, then just sit on the rest.
Many of them are not so called 'weak hands'. We have here very many market speculators that use their big amount of BTC to sell high and buy low. This is happening right now but of course there are more factors.
