Bitcoin dropped to around $8,300 after a few days of trading at  $8,600, likely with more room to drop as it looks to find support. If  bulls fail to hold at this level, key short-term supports are seen at  8,000 and 7,800. If this is mere overselling of the recent bounce, then  we could see a push back to 8,600, where the 10-day MA and EMA are at.  Looking at the longer term price structure, BTC will still need to turn  $9,500-$10,000 into support in order to lock in a trend reversal.

Global market cap is at $229B, while BTC's market cap is at $152B.

Square has also announced on its blog on Jan. 21, the start of a Lightning Development Kit (LDK).  LDK is reportedly larger than a node and would customize experiences  for wallet and application developments including API, language bindings  and demo apps. One of the issues discussed with regard to lightning is  its "shaky" infrastructure but the company said improvements would lead  to low-fee bitcoin payments "as common as cash used to be."
