The altcoin market continue to be destroyed. This is a leading indicator for what will next happen to bitcoin itself. Heed these words: cut your loose before it's too late!
Your words would make a little sense if bitcoin didn't have the infrastructure that it has. The alt coins are nothing but trying to get rich schemes on the tail of bitcoin. I have predicted the fall of most alt coins for a long time because there is very little support outside the alt coin world. How many times have you seen litecoin or another coin mentioned on the news? I never have.. So, while bitcoin could really take a hit, it will survive..
I don't think he was saying alts are great... I think he was saying that in the last few legs down the alt coin markets were riled first and then about a half hour later BTC started a leg down.
