Checking currently coinmarketcap.com, Bitcoin reached a new all time high way over 5500USD; currently it shows it as 5626.48USD for a bitcoin which is an increase of about 9% compared to the last peak. Roughly 75% more then what the rate was a little over a month ago. Hope you all invested back then.
Reasons behind it are speculated by analysts to be the expected technical change that will be implemented later this month with the upcoming fork of Bitcoin Gold; like it was done with Bitcoin Cash end of August, to spread the digital currencies even wider. Although if you look at the current rate of Bitcoin Cash, which is 321.08USD right now, we have to see, if that plan will work out to be successful.
