I made an example of bitcoin logarithmic chart, with the existing uptrend which never broke.
Becides that in chart you can see, that every week that passes, there is a higher "lowest point", and it grows per ~100usd per week. Since this is historical chart and as we see that bitcoin never disobey following that trendline.
So million dollar question. When ATH?
Chart says by the end of 2020, without any significant parabolic ride. If there will be a parabolic rally, then Bitcoin could reach over 50,000$ by the end of 2020.
Buckle up, buy all low levels and find your exit strategy :-)
