I have been waiting for a week like this for a long time
there were too many crapcoins out there that ought to have died long ago.

and here's this week's list: (on cryptmarketcap.com 7day price% drop >25%)

NXT -33.15%
Aurora -88.0%      (whoa, gameover man)
Quark -26.0%      Just keeps sliding since mined out.
Vertcoin -26.7%   Was a fake pump, and everyone knew it.
Primecoin -33.6%  How it is still here already is a good question.
Megacoin -30.0%  about time this monkey show dies. KGW recently proven inferior.
YBcoin - 28.41%    This is a china coin, guess I never get to know it.
Spaincoin -64.2%   Another Joke that ought to have dispersed before it started.


If you still have any of the above, you probably best off switching to a coin that have hope.
I have my list of hopeful coins, but I know no one agrees to that. (which is fair)

though the drop of the above list is for all to see, and to be honest, an investment that can drop 25% in 7 days?
lol, you know it is a joke. 

my advise is GET OUT while you can.
