It is always a bad time to buy against the trend (currently the trend is bearish).
So, I'd say no
There is no one trend, a price function contains many trends over many time periods.
All time should be taken into consideration when analysing.
The recent downtrend is a "sub-pattern" of the overall fractal like structure.
We are approaching the end of a triangle, and so we will see reducing volatility (tightening).
And then it will break out. The question is will it breakout to the upside?... Well given current market volume and past performance over very similar patterns I think yes.
So yes, now is a good time to buy, sure you may scrape a few more dollars if you're lucky enough to buy the perfect bottom.
i think that this picture says it all. seriously those patterns are so alike its almost scary and if anyone isnt buying right now then i think they need to rethink what they are doing because now is the time. price will be 5000 within a year
