while i am trading sometimes - and yes, even shorting sometimes - i still follow the plan that i made around the last ath: buy as long as btc is below 1000$, then wait and see.
i am in with a moderate amount of money and wrote it off as "spent", so nothing in the world would make me sell the stuff. edit: yes, exactly, i would ride it down to next to nothing.
my current mindset is ... well... i shorted recently, but just to increase my stack of btc. right now i think that the risk of having to rebuy at higher prices, thus resulting in a btc-loss, is higher than the possible reward of another downswing. sure, there are some indicators pointing towards a retest of the recent low, offering a chance for 10%ish gains. on the other side we heard a lot of very interesting stuff this year that - in my opinion - has been neglected in price formation to some extent because of the downward momentum. the rule of buy the rumor, sell the news has been overridden and might lead to a reversal if people are confrontated with the results. that happened - in my opinion - because the current players involved in btc are not able to understand the mechanics that are currently working behind the scenes (outside the exchanges). honestly, most of the so called "investors" right now are more or less grown up kids with no to abysmal small knowledge about money, investments and economics.
since i am risk averse and in overall bullish, i stopped shorting recently and will compensate further price drops with additional buying. on the other hand i still see a possibility that btc might fail within the next 1-2 years, resulting in prices around 1$. but right now the btc-investment has moved from "pure lunatic stuff" to "highly speculative asset", and thats something.
