Base on my opinion and studying about bitcoin. Because bitcoin has an unstable value. Maybe it will be. But! Bitcoin is increasing every month.
However their is bothering me. Is bitcoin price is still like this next month?
As you say bitcoin has unstable so what the price would be by next month is quite hard to say but due to growing networks and people being aware and having interest investing on bitcoins it's easy to say that it's more stronger and safer than before.
