From what we can see, we had PPO bull div on 3D - 3 times in BTC history according to BITSTAMP:BTCUSD. The first two times it occurred we had a price increase of 61% and 67% approximately.
Price increase is calculated from the closing price of the candle when the bullish PPO divergence occurred until the nearest higher high.
Let's see if it can happen again.
I'm staying Neutral - holding.
