If I could predict in 2017 there was some progress than bitcoin. As many know bitcoin so much to use and adopt. Moreover the price in 2017 will be better than this year. Maybe it was a definite change occurred in bitcoin 2017. I also hope that the scam sites on bitcoin will be reduced so that it will be easier to use.
After too many scam sites run people money I think now they already learn a lesson and I agree 2017 will be big and the scam sites will reduce thier innocent victim.
Till people will keep on entertaining those sites by investing their money, those sites will always keep on operating, people should understand the fact that there is no formula to double coins.
There is always a formula because it is possible to double our money in bitcoin but there is also a possibility we lose our money instantly, everything is a gamble here and we are only basing our decisions on historical and present facts to have at least an understanding on the right speculation.
