I think Bitcoin never went down or being outperformed by some other Altcoins. A large portion of these Altcoins are up for a demonstrate that they didn't last more while Bitcoin isn't doing anything. These arbitrary Altcoins are continue appearing yet never last more, they were much the same as a degenerate government officials that continues promising however aren't doing anything after they win. However, Bitcoin may go down for seven days yet no Altcoins could ever going to outperform its value I presume.
