Every single coin is going down in the list. I have never seen like this where every single coins go down. I have seen where most of them were down but at least 10 or 20 coins were up.
But this is the first time where every single coin is going down. Did it ever happen before?
Yes , it happened a lot of times.
When BTC reaches a certain level after the enormous growth is over and we see corrections, the alts turn to bloody red.
And it is pretty normal, their whole existence is tied to bitcoin, that's why the name "altcoin".
When bitcoin sneezes, better not be invested in superdupacoin or alladinpocahontascoin. Some of them never recover after a crash as poeple turn to megadupacoin and pigletmousecoin.
Besides, that pictures of yours contains two altcoin even worse than he normal ones.
Two useless forks like bcash and bdiamond which I do hope we won't see in the top 10 next year.
