The real issue here is when it will hit rock bottom.
Besides that, it's not the first time cryptos goes down and then up again. I remember a similar slump back in 2014, and let's not forget the first time BTC got to the news as a currency used on the Deep Web.
But after all, we have to remember, this is NOT an investment instrument. Prices will go up and down.
I'm not sure what you mean "this is NOT an investment instrument."
