Please read this post (again?) and look at the charts.

All coins have fallen a LOT with respect to December/January. There are some few exceptions that just had a pump (EOS) or generally did better than average (Decred, Ethereum), but almost all the remaining coins fell significantly more than Bitcoin. 85% losses with respect to the ATH is "the norm".

The reason is simple: Altcoin investors assume (we could also say, they know, as this happens in every bear market) that Bitcoin holds its value a bit better than almost all altcoins when general cryptocurrency prices are declining. And so they sell their altcoins and hold Bitcoins instead. There is also the part of the audience that needs to sell their altcoins to BTC prior to "cashing out" to fiat - another reason why altcoins fall more sharply than BTC in bear markets.

I'm a cryptocurrency user since 2013 and already went through a whole bull/bear market cycle, so I think I know what I'm talking about. In 2014 the pattern was almost identic: Bitcoin falling slowly, altcoins crashing hard.

To break that "altcoin curse" and escape the bear market, a coin needs to bring up something really good & unique. PPC 0.7's cold minting can be such a feature. A website redesign isn't.
