Don't even bother checking the price movements because it's pointless.
I couldn't possibly disagree more. Fuck buy and hold during these times.
Very simplistic view you are taking there, in your case yes maybe, it depends really at what stage you got in at and the level of your exposure and what you can afford to lose etc..
The main point is that if the guy has to ASK the question he's probably not capable of executing any sort of worthwhile trading strategy in the short term so in his particular case it's probably better to make a long term bet on BTC and only invest what you can afford to lose.
I've been buying and selling all damn day, my trading volume has gone through the roof. 50% of my coin is in long term storage. The other 50% I'm trading with. Though I'm mostly out at the moment, it's been far too stable for me the last few hours so I can't call it either way. A few wild swings is what I like
