When thinking about strategies...
Two more thing come to my mind:
- after another post: some mention a time lag in the trends of the 'following' altcoins vs bitcoin... which could be helpful. I can see that as a theoretical possibility...but not how to use it exactly...For future research :-)
- maybe the logic itself but: don't judge a coins +/- trends on the trading pairs in your exchange (as the paired currency's trend can create a false impression) but on their absolute value on coinmarketcap...
[Edit: learning as I speak... I just saw JK mentioning in his videoblog there's a hughe risk of USDT collapsing... endorsing your last point :) !

Very good points as well! The laggging trend is interesting one and worth exploring more. As for the true gains and losses of an alrcoin, that is absolutely true! I wrote about this exact thing few weeks ago when ETH was having a bull run and made all ALT coins to drop in price. You can read more on this here.
