Well, it doesn't hurt to take a cautious approach either. If you power down a bit now and put it into Bitcoin (which does look set for further gains), and the Steem price continues to decrease, you can buy back in later and get more Steem than you started with. This would be much like the strategy I'm using for REP. However to do that really effectively you have to play the "guess the bottom" game.

Another factor to consider in that strategy is you lose out on some of the "interest" from holding Steem Power. But right now the price is going down much faster than that interest is accumulating, so it might not make much difference.

It's a trade off, and hard to see which approach is best without knowing how close we are to a bottom.
