The first point must be applied to all times. You should also note that during the crisis mostly p&d coins are making x2, I've been looking on top gainers on CMC and during the dump that list was full of shit. The point 6 is probably the most usefull one, expecially if you made some fiat reserves at the high pice of BTC. You can also try to lend some of your coins to get a small profit but trading during that time will be toonervous and it won't woworth it.
