It's nothing to be worried about , we have seen it 250$ or something last year so unless It reach that price , no worries.
It's probably some manipulation for exchange to buy at a low price.
Absolutely nothing to worry about, you're right. People with half a brain are invested in bitcoin for the long term, this isn't a get rich quick scheme, certainly not since the Gox disaster.
Patience in bitcoin will be rewarded.
