Bitcoin hasn't lost any momentum imo. The market thinks 10k is an important level for Bitcoin. It's not; it's unit-bias. I would even go so far as to say there are still more buyers than sellers even now. There's just a small majority of whales who bet against the market during times like this. They're going to get burned.
All the actual momentum is coming from the halving event, and no amount of random news is going to change that. These little hiccups mean nothing. Can we even call it a dip? The change from $10500 to $10100 is only 4%. Maybe in the stock market that's a lot but in the cryptoverse that's simply normal day to day behavior. In my view the real dips are the 25%-40% retracements.
The market is building pressure at this unit-bias 10k level. Price is being suppressed by nothing but fluff, and when that fluff disappears Bitcoin will spike up to 11k or beyond in less than an hour. The market is going to remain overwhelmingly bullish for at least another 6 weeks as halving hype gets stronger and stronger.
RE: BTC - What caused the dip in Bitcoin today? More sellers than buyers...
