Actually I calculated devcoin's value and it is up in actual value, just not as fast up as bitcoins.
So to me it does not look like altcoins - or at least devcoins - are crashing at all, they merely are not skyrocketing as fast as bitcoin is.
Take a look at the charts at
http://galaxies.mygamesonline.org/digitalisassets.htmlLook at a chart showing values in terms of something that is going up fast, and it looks like everything else if going down.
Look at a chart of something that is going up slower than most other things and most things will look like they are going up.
Its all relative.
