This is probably a panic selling. Its already obvious that we are still in the midst of bearish market. Typically a holder wouldnt even move a budge just to sell it on a desperate attempt. But our situation with all the markets are down, some cant be blame for selling and fear to lose their asset some value. Anyway, the market already down by huge since last night and still going down more. I am afraid it would touch down 3k level if this continue.
There are several times that we encounter this fall and those coins doesn't move and its a mystery on why this one move at this point well maybe the old owner got panic from a huge market upset since as of now we don't know on what is the deeper price come since the virus is so strong and hurting badly the economy, so provably the owner moves that since that is his last defense for his losses recently.
As I said above, it's not panic sell, it's a guy who has a lot of BTC in a flash drive, from time that BTC was mined by GPUs
Incredible, but true
