It's nothing out of the ordinary. It's simply a correction, that was bound to come sooner or later.

I'm not sure why you'd expect anything else, even, given the fact that the growth we've seen over the past week was simply unsustainable. The rallies that we saw up to $13k+ was mostly a result of FOMO buying due to the hype of BTC going through the $10k resistance, which has psychological significance to investors, and perhaps some short squeezes as well.

These short term cycles are quite common in any asset class, not just BTC. I don't think that buying at that level was necessary a bad trade per se, given that you have the patience and belief in BTC in the long term. It seems like the $10k support has been tested and it held up nicely, which is a bullish sign.
