Hanging over the market still are concerns about next week's G-20 meetings (and the possibility of a more global standard for cracking down on cryptos) as well as the massive Mt.Gox sale overhang.

Nobuaki Kobayashi, bankruptcy trustee for Mt. Gox, the largest bitcoin exchange in the world before hackers absconded with tens of thousands of customers' bitcoins worth billions at recent prices, said he started selling in late September, meaning it's quite possible he sold at least some of the coins at the highs reached toward the end of last year.

Still, Bloomberg reported  that Kobayashi is sitting on another approximately $1.9 billion, which he says he plans to offload soon...

However, with Bitcoin battered back below $8,000, it has entered the "Mystery Dip-Buyer" Zone.
