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.
They are just expressing what they think it is going to happen and nothing more, no one can give guarantees in this market with the high volatility that we suffer every day, however it is entirely possible they are right about heir prediction or that at least they are not that off, after all we know the market will eventually recover and even if we do not know when, the longest the time frame the biggest the chance of a recovery happening, and since I believe the price will recover in the next 2 to 3 years it is possible their prediction comes true or at least it is close.
