While I also think that bitcoin is not going to die in the near future and am positive about long-term perspectives, I do not think we will see $25k this year. I'll be very happy to see $10k again, but now I doubt it will happen in 2018. The cryptowinter will last for at least a year, maybe two.
Try reading graphs from previous of crypto. I guess you are not familiar with bitcoin price history. This year will gonna be the start of when cryptocurrency will be fully known in the world since many big-time investors are now starting to switch from banks to bitcoin. Blockchain technology really cool and worthy to invest compared to traditional investment.
