Periods of stagnation in the market are common as is swings. Observe the long term charts and you will realise that the yearly volatility is usually under 15% and thus I would not compare the market to be that volatile that it can be said to be non-volatile now. It rather remains in its own movement that is often exaggerated as too high or too low.

Overall I think the stagnant market will be a good time to buy at the low since it's much lower than all time highs. But a trader should keep both cash and Bitcoin at hand to face the upcoming bull or near market respectively. If the market remains stagnant, just observe and wait it out.
