Bitcoin [BTC] - Update 26/04/2018
Looks perfectly fine to me. ABC etc. Never a straight line up. Of course, also listen to the people who predict a more bearish scenario (not those simply calling out numbers, using crayons on charts or that have outlandish theories) and then make up you own mind. We could go down a bit more (zig zagging all the way), but as long as we stay above 8.5 (or even 8.1 according to some) we are simply following the pattern up. And to go up, you sometimes need to recharge. The ups and downs are where the traders make (and lose) money. Lots of trading means lots of volatility.
If we stay above 8650, we are probably in Wave 5 (after the Wave 4 correction), if we dip below, we are in the Wave C of the ABC correction before starting Wave 5. It doesn't matter if we go up or down on the 5 or 15 min timescales. A Wave 5 also has an impulse pattern and is not a straight line up.
The FUDsters you should ignore completely by the way. They are either bot posts or they might as well have been.
Good luck.
