One thing I noticed during the bull run of December 2017 are some of these numbers on Coin market cap and how drastically different they are during the bear market. At the height of the bull run we sat at almost a trillion dollar market cap. That would of been a huge deal if we did hit a trillion, as it would be the first space to have a trillion dollar market cap. This was before Apple achieved that as a company. Another thing I noticed with BTC dominance, is that it was very low. Probably because it was season of the Altcoin and everyone was allocating funds into new projects.
As of today bitcoin dominance is high and its total market cap as a space is very low. It's climbing though as just 2 days ago we sat at a $200 billion market cap now it's $216 billion. Its slowly climbing up. Bitcoin dominance is slowly receding as well. Its either the start of a bullrun or a very hungry bear trap.
What to look for in the start of the bull run or any movement is the total market cap of bitcoin, and then look at the market cap of the space as a whole. Also check bitcoin dominance. Those are all indicators of where bitcoin might be headed as far as price of bitcoin is concerned. Right now we are seeing green everywhere. Beware of the bear trap.
