Looked at altcoins and they've started rallying pretty hard all at once, whats the reason for this? Is it because of Bitcoin going sideways for a decent while or some other reason?
I think at the moment we have to look at the market as a whole rather than individual coins. We bounced back twice quite sharply from whole market lows of about $270 billion. Then over the last couple of weeks we have dipped a bit below that. The latest mini-rally has pushed the whole market back up to $270 billion. As far as I'm concerned, this is a sign that this could be a fairly stable minimum. Essentially, again my own perspective, we have been falling for months and now there are the first signs that we've hit solid ground. Once this is more firmly established, we can anticipate the whole market moving upwards again.
