According to Coindesk, the cryptocurrency clocked a high of $6,736 on Bitfinex last week amid signs of a bear breather. However, bargain hunters were short in supply and prices fell back below $6,600 at 01:00 UTCtoday. Bitcoin has spent a better part of the last seven hours trading in the narrow range of $6,550 to $6,620.   In addition a grey cloud hanging over the heads of cryptocurrency investors was lifted last Thursday after the Securities and Exchange Commission (SEC) ruled that Ethereum is not a security.  Blockchain's strong year continued when The Wall Street Journal released its annual list of "Tech Companies to Watch." Of the 25 companies selected, five are blockchain initiatives. Last year, no blockchain-related companies were mentioned. The highest ranking company, Blockstream, is developing tech for Bitcoin micropayments and cryptocurrency data feeds for traders. Active tech companies today include: SinglePoint Inc. (OTC: SING), AppSwarm, Inc. (OTC: SWRM), Net Element, Inc. (NASDAQ: NETE), Seven Stars Cloud Group, Inc. (NASDAQ: SSC), Glance Technologies Inc. (CSE: GET) (OTC: GLNNF).
