It's just a drop in the bucket, demand for bitcoins would absorb this sale without significant drop, but people are so freaking out that it will doom Bitcoin price by 30% or more that they are selling from FUD, thanks to all these pseudo media news.
Relax, go swimming at the beach, walking on a mountain, focus on important things and if you need to buy something expensive with bitcoins, wait a few months if possible, if not just hodl and don't care.
