I personally think bitcoin will increase but not expecting $5000 by this year without any big events. I think $5000 in 2018.
Its pumped super fast over the past weeks and doubled in under a month. Assuming that happens again, or even if it pumps much slower I don't see why $5000 won't happen this year.
It won't becausee there is too much hapenning with Bitcoin at the moment.
Still no scalability fix and our Bitcoin just got threatened by Jihan because of the UASF coming soon on August 1st.
https://blog.bitmain.com/en/uahf-contingency-plan-uasf-bip148/Considering all that has happened recently, I imagine that Bitcoin is only alive because it is the pioneer in the world of cryptocurrencies and is already accepted and stamped as the "virtual currency" all over the world. Just compare Bitcoin with other currencies in the market and you will see how expensive our fees are, how slow our transactions are and how divided our community is, which ends up destroying the currency and its growth in the future.
I imagine we could have hit the $5000 some time ago if it wasn't for all this problems keeping Bitcoin's growth stuck.
Keep your Bitcoin, but also buy promising coins like Dash, Decred and Litecoin just in case.
But in a case that bitcoin survived that August 1 happening, surely bitcoin will give us another new trend. The hype it will build will become more stronger and soon that $5,000 target is achievable.
Honestly Im worry with that as time closes by but like in the past, there are lots of major events that wants to changed what bitcoin is but never become a succesful. Hoping for the best here.
