I was reading the Speculation section from the Economics forum yesterday, and two guys from the BTC Foundation said that 2018 will be the last time that Bitcoin will be under $10,000. I believe that this statement was made to lessen the worry that comes about every time that BTC drops. I don't know how anyone could make that statement in full faith though, as the nature of altcoins is its very volatility. Since it is not tied to normal economic conditions as fiat currency is, I don't quite see where that prediction comes from. The fact that many economies are talking about some type of oversight does show that acceptance is gaining and perhaps is a harbinger of more stable, and higher, prices.
It is true that no one can assure you that price is not going to go any lower than that, in fact it seems very likely that this year of 2019 is going to start with a price that is lower than that but it's likely that during the next years the price of bitcoin is going to recover and go up once more and everyone will be lamenting not buying bitcoin before it reached that price.
