It would be a terrible thing if the Bitcoin pattern is the same as in 2013-2015, it could be the end of 2018 is only about 4000 $ -6000 $, as I think if it might happen?

What if it really happened, give your opinion?

I believe that bitcoin prices in 2018 will not only fall back to the $ 4000 level but may fall further and possibly reach $ 1000 by the end of 2018. You can see that bitcoin prices are constantly fluctuating and falling. strong since the $ 19800 mark. City is falling into crisis as bitcoin prices are constantly falling. So at this moment I believe bitcoin prices will continue to fall sharply more than the global recession.
