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.
In general, the normal market by default assumes some element of uncertainty, that is, to put it differently, it is part of the rules of the game 
And a really good enough option was a correction to the area of 30,000, and not below. I agree that due to the ongoing pandemic and, accordingly, the continued pumping of money into the economy by state governments, there are the worst hopes for the continuation of the bullish trend.
