Despite an already six month cool-off period, for 2018 we see more sideways and downside potential in the bitcoin price due to sluggish retail demand, hesitation from institutions and a current market cap that seems too high relative to the activity occurring on available blockchains.
Many investors and advisors are on record stating that $5,700 was the bottom in bitcoin for this year, and that higher prices lie ahead. While we are very bullish on bitcoin's long-term prospects, we do heed caution for more short-term price optimism.
To find the starting point of the historic parabolic rally in bitcoin that ended at $20,000 we have to go as far back as August 2015, when bitcoin traded at below $200. This past rally was a stupendous, historic move. Even in secular bull markets, the collective of economic actors need time to absorb the information embedded in its characteristic high volume rallies.
As I've indicated in my 2018 outlook, I think chances are high for this year to be remembered as a shakeout year: a lemon market in altcoins, regulators catching up and infrastructure growing pains.
Short-term bearish signs
Since January, the bitcoin mining hashrate (aggregate computations per second made to secure the network ) has tripled, which means that a huge amount of new or more efficient mining rigs have come online. In combination with declining prices, this means that miners who weren't able to upgrade their machines or find cheaper electricity have been faced with a steep decline in profitability, a 90% drop in 7 months (altcoins have faced similar or steeper declines).
With profit margins under heavy pressure, it's not unlikely that miners are and will stay responsible for a significant amount of selling in the market.
