It's not unusual at all.
We have these threads periodically.

No, seriously, from time to time these threads pop up, just because it goes sideways for a few days/weeks doesn't mean the price is becoming stable.
When it was at $800, $450 and at $660 last year it went sideways for far longer than now, look at the chart.
The sideways is perfectly normal but it's only temporary before another big move (probably a dump) which should come in 4-7 days. There is no stability.
