Not only this analysis but there are lots of analysis available in the internet where it is clearly saying that bitcoin is no more limited to 10k$ per btc but it will again starts to get high with again and try to touch new record of 30-40k$ and this amount will not be the small now because this time increase in btc price will be with better stability and there will be no chance of big dump like today we are seeing in bitcoin .
So may be this analysis of 30k$ will be small , Because my opinion according to my analysis is about 50k$ will be in the mid of the year 2018 .
