As I expect, this rally is short-lived. There is really no momentum for a bull market to break out at the moment, so it's just a short term adjustment. The resistance at $7500 was pretty strong, as expected as profit takers seem to be selling as soon as market picks up a bit.
There will be some more dips in the following months, followed by small rallies following those dips, but in general it is safe to say that we still have some space to go down before consolidation at the bear market's bottom can fully occur.
I agree with almost everything you said, except the the profit-taking part. It looks like the whole market switched into a day-trading mode of operation, but it is not necessarily profit takers who don't allow the price to rise higher. The swings are too small, and it may be an artificial resistance created by someone who doesn't want the price to rise. Today, when the market sentiment is all doom and gloom, it won't take a lot of financial resource to keep prices contained and constrained, especially to the upside.
It could be. However with any sort of pump there is going to be profit takers, whether that constitutes a small or large percentage. I suspect that most big players now are probably trading bitcoin for the short term movements, either shorting or going long for a few days/weeks at a time with margin, otherwise they would not be selling as soon as there is 8-10% rise in price.
The artificial resistance that you mentioned could be possible through a group of shorters, or just someone with a huge stash of BTC bought earlier.
But overall as I've said, unless a sizable short squeeze happens due to a sudden reversal in the market sentiment, we're not going to see any major bullish activity for the time being. And even if a bull run starts occurring, there is reason to suspect that it's a bull trap if prices have not plunged further and consolidated there before making its way up.
