I think that experience has shown the great futility of technical analysis to make accurate predictions about the future performance of bitcoin. In previous moments, many predicted that the lines of $1,000, $5,000, $10,000, $15,000 would be important resistance levels, but were broken without any problem by Bitcoin. What is a fact is that it will be difficult to repeat a period of speculation as intense as that experienced in 2017, but we all know that almost everything is possible in this unpredictable market, so it is really worth to keep and hold some coins for long.
Anything that has to do with predicting the future of a price of any market is always going to remain as a speculation that is bullshit. The best anyone can do is to always blend with the trend, and as far as btc is concerned, you really have to be ready to always make very quick decisions in the market so you do not end up screwing up badly eventually. TA should be a guide, not some wand to give you what the future holds, which is what so many people always expect and that is bad.
