i think 2008/09 also had several legs down of stock market over several months.

So it would make sense that this is just the first of several stock market dips.

I personally think DCAing BTC is easiest way to balance risk and reward.

I experience more pain when I wait to buy BTC than I experience pain when I buy and the BTC price goes down.

however, i think it's smarter to keep diversification of some cash and set buying limits down, but this requires patience and discipline which I don't have.
