Yeah it was very healthy. High volatility means uncertainty and uncertainty kills financial instruments. So bitcoin's pull to 30000 was healthy because it came after its raise to 40000 so quickly. Meanwhile I personally believe 30000 was just correction and bull run is still not over. It is hard to find entry point in these prices but Bitcoin is still BUY and HOLD for me.
We will know it's a correction if it rises above its current prices. Since nobody can predict when the bears are going to take over, it's definitely safe to have good risk management (if you are trading) and accumulates more (if you're a HODLer). Remember that there's always going to a stop to a trend; whether this bull trend will end or not, it's not going to be forever for sure. It's better to focus on the bigger picture or the long-term part, as they say, with every investment. Just be patient and plan.
