** What will come 2018?
Its unbelieve and scare (on a good way)
The scary part (on a bad way) will become when bitcoin price increases with 1000 USD every 24 hours.
This speculation bubble will be the biggest in the entire financial history and the market madness will lead to somethng very bad for all the newbies and small investors.I want a more stable price growth,like it was at the top of your "shart".Bitcoin price should grow with 1000$ for 1-2 years.This will make all the speculative investors run away and only the real btc users will remain.
