Looking as to why bitcoin is down
people are selling bitcoin or buying altcoins with great possibility to x10 or more in value with bitcoin price now a double your money in an instant is impossible so most holder now are getting altcoins to make their profit more great. in due time people will sell their tokens just to be back in bitcoin community. so no worries on this!
If this were true you would see an increment in the altcoins' values as always happened before, but it isn't true now.
