I noticed this interesting trend as well. Some of the altcoins are going up in relation to BTC but, ultimately, when BTC drops, the altcoins drop even more when compared to fiat. I honestly don't know why altcoins are so affected. If there is panic about the fork, I would have thought the best course of action is to move to a strong altcoin, for example, Litecoin. In hindsight, shorting everything to Tether three weeks ago would have been great but shorting is risky too ... and you can't sleep as its 24/7 activity.
