I'm sure and optimistic that this year could be better than 2017, even though there's a lot of negative news about bitcoin and a lot of users are panicked and selling bitcoin but I'm sure that bitcoin performance will soon improve and the end of the year could reach at least $ 50k.
It's too early to speculate about it since we are still in the midst of the year 2018. But for me, there's a great potential that this year would be better than 2017. If ever the marketprice of bitcoin would go bullish before this year ends and will go beyond 19K$, then I would conclude that 2018 is better than the previous year. I strongly believe that btc can achieve such price.
Definitely, it was just in the midst of year and really hard to predict on bitcoin's future. But I am still hoping that bitcoin's price will highly increase at huge amount by the end of this year and may reach as low as $ 50k. And I believe that bitcoin is much better this year 2018 than last year when it can reach the desire amount.
