My suggestion is keep it in #Bitcoin and have a long term perspective. The short term volatility will matter less and less as time goes on, and it will matter more and more the longer you hold cash.
Savings is specifically a long term security strategy, don't shoot yourself in the foot by sacrificing its long term usefulness over short term concerns.
In other words, if bitcoin is volatile in a downward direction and something bad *isn't* happening, then use that opportunity to save harder and it will pay off even more when it returns to the mean.
