i think it's normal to think the price may go to below $400 levels as bitcoin has surprised many of us plenty of times already. i think this month we'll make an attempt to reach $450 as we're heading towards the block halving. but then again, i don't think we will be able to hold $450 for long as the price will get dumped down again.
Why $450? Has there been a lot of buying around $450? Apart from that possibility, I'm not seeing anything about $450 that suggests there'll be resistance - the only significance I can see is that the last peak reached $450 - but that was in the context of lower peaks, higher troughs.
I expect resistance around $500, however, due to the November high.
the market is currently in state of repeating. we have seen the price move in the direction of $450 before, and it didn't even make it to that price level. for some reason it won't go much above that price level, and yes, i agree that the charts don't show anything special at these levels, but i find it very weird though.
the reason is because of the sell walls that was placed in order to keep the price from going any more higher which i find a little strange but i have seen this happening.
