Regarding volume in the recent upsurge of the past 2-3 weeks, this most recent upsurge has been on low volume, and there may be some signs that it is picking up a little bit of steam in recent days - it's probably too early to determine where it is going, but the price increase of the past 2-3 weeks has been on relatively low steady volume (possibly slightly increasing and not shrinking volume).
You talk of 'manipulators'.
Well, I talk about manipulators because I remain of the belief that we have to continue to account for such a dynamic in part because bitcoin's market cap remains relatively small, and there seems to be a considerable amount of both financial and political incentives to make attempts at manipulation.. .yet manipulation remains only part of the story, and likely harder to achieve the larger bitcoin becomes in several ways, including price pressures by a larger and larger variety of actors.
Prior to the break out at $435, which was also the breaking point of the last viable triangle based trendline, there was 17.5K BTC swaps on Bitfinex. During the rise, that total cratered to around 12K. That right there, is 5K of pure unadulterated buying pressure. I am off the opinion, that BTC has been driven up, because that is where the easy liquidity is to be gotten and now that 'they' have got all of the 'weak' shorts, Bitcoin will now correct....with the odd little cheeky pop up above $455 just to srping any Johnny come lately weak Short Stops (i.e. risking against the recent high), also being likely.
I don't make any meaningful attempts to predict shorter term price moves or even potential's for quick 10% to 15% adjustment of the price based on short term momentum that may be caused by a narrow set of factors. Some of this is just difficult to know for me and probably for anyone except someone playing with a lot of coins, and I don't want to spend that much time analyzing the various exchanges in order to make such attempts at short-term price predictions... Accordingly, I attempt to prepare my own buying and selling for at least a quick and unexpected 15% price surge.. and then to readjust along the way in case the price surge continues in the same direction (or the easier outcome when the price momentum nearly immediately reverses directions). These days I try not to run low of either fiat or bitcoin.. even if there is a price surge. .and anyhow, my trading amounts are not really a vary large percentage of my total holdings... which seems safer than trying to bet on short term green or red, which seems nearly impossible.
However, I am totally with you on the $350, $360, $390, $403, $412, thing. I have been keeping a close eye on it myself and along with that, and the line in the sand final resistance trendline at $435, which I did not think would be breached on this attempt, I have been looking for a breach of this level, followed by a support of either the trend support trend line, or the final resistance trendline which should now become support....
O.k. We know that previous price points remain relevant... showing either areas where support or resistance builds up - . yeah and breaking through those can cause trends.. or changes in trends, yet we may remain unclear about interpretation while in the middle of it.
....thus I am looking to go long, but I aint buying up here. BTC will correct soon enough.
Personally, I believe that is a risk and a problem when you play too much balls to the walls, and it just is neither my style or my tolerance. I would rather set up my strategy to for sure win in smaller increments rather than gambling and winning bigger (with more uncertainty)... ... but different strokes for different folks... you surely can win bigger when you gamble, and younger people can still make up for screw ups... the older you are the more you also need to preserve your capital (but still hopefully able to use the capital before death - because it is not going to do a lot of good to build up a fortune and then never be able to use it because of death).
