Just kidding. It's not the end of the world. Sit tight and ride it out, and the upward trend will probably resume. While cryptocurrency prices are falling suddenly today, I have been expecting this for a while now. The trend is consistently upward over time for established coins and coins that add real blockchain innovation. The last month has just been abnormally strong, and a correction was inevitable.
Perhaps even buy more coins now, since they are all "on sale," so to speak.
