I think with the current trend of bitcoin pricing in the market which is currently in a "trap". It can't even go above $10k and always fluctuating around $7k-9k. I assume the pricing would pick up again starting Q3 of this year. Same as last year where the demand suddenly spikes up and pricing went wild. Therefore, I believe bitcoin will not be $1800 by the end of 2018. The pricing could be around $15-35K depending on the current demand and direct fiat conversions.
