For example, on Dec. 20, Bitcoin miner Greenidge reached an agreement with its creditor to restructure $74 million worth of debt — although the deal requires the miner to sell nearly 50% of it equipment.Moreover, publically listed Bitcoin mining company Core Scientific reportedly filed for Chapter 11 bankruptcy on Dec 21. While the company continues to generate positive cash flows, the income is insufficient to cover it operational costs, which involve repaying the lease for its Bitcoin mining equipment.During these events, Bitcoin has held $16,800, so there are buyers at these levels. But let’s look at crypto derivatives data to understand whether investors have increased their risk appetite for Bitcoin.Bitcoin futures are back to backwardationFixed-month futures contracts usually trade at a slight premium to regular spot markets because sellers demand more money to withhold settlement for longer.

Therefore, as long as the $16,500 channel support continues to hold, bulls have reason to believe that another shot at the $18,400 upper band limit is viable before year-end.The views, thoughts and opinions expressed here are the authors’ alone and do not necessarily reflect or represent the views and opinions of Cointelegraph.
