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?
Let's look at the pattern in 2013-2015 below:

Anything can happen. But no one wants negative events and losses. I thought bitcoin could reach 7k at the end of July but hopefully in SEC ETFs more than in August. I do not believe these bad cycles will repeat this year. This market stage is vastly better than ever and the user base and investment are increasing every day.
