The change in price action patterns for the first time in a long while is due to the fact that the bots algorithms have been updated.
Change means change and implies change.
If the bots have ben changed, it is because we will see change.
We've been living through an uptrend and change can only mean something different; a downtrend.
It will be apparent within a few days and maximum a week or two as the change took place only a few hours ago and it takes time before its spreads out and becomes evident all across.
The market sentiment reached "extreme greed" for the first time in a long while. The highest reading in more than two years if I am not mistaken.
Bitcoin traders, buyers and holders are currently feeling extreme greed. This metric alone should be cause for caution.
At this point, caution is advice by all conscious, intelligent and avid traders.
I can tell you something with 100% certainty: This might not be the top, but I am 100% positive that this isn't the bottom. Bitcoin is trading at its highest level in more than two years... Stay safe.
Namaste.
