I don't think that the current decline is as a result of panic dumping per se.
It's honestly just a natural part of the cycle that we are in. We've seen huge bullish rallies in the year of 2017 and thus, there will be corrections sooner or later, and that happened within this year.
That's the simple fact of it. The market sentiment has turned bearish because there hasn't been much activity within the market since the start of the year. There is absolutely no reason to panic and every reason to buy and use dollar cost averaging to your advantage, though.
