Bitcoin in the News : 2017-10 Price

In last month's post, Bitcoin in the News : 2017-09 Price, I wrote, 'I must remember to prepare the chart on the first of the month rather than for the first post'. In this I was successful. In the previous month's post, Bitcoin [Cash] in the News : 2017-08 Price, I wrote of the monthly chart, 'The following chart might be captioned, "Straight Up!".' The same goes for the current month's chart. In trying to understand why it went straight up, I was unsuccessful.

Bitcoin (BTC) Price Index

As in previous months, let's look for clues to the price action in Cointelegraph's Bitcoin Price Analysis (BPA).

• 2017-10-03: Why is Bitcoin Price Slow to Pick Back up to $5,000? • 'Bitcoin price continues to increase in the stock market and remains on course to reach the $4,500 level after falling below $3,000 due to the regulatory campaign by China against cryptocurrencies'
• 2017-10-10: Bitcoin Price Flash Crashes As Russia Proposes Crypto Exchange Ban • 'Russia’s central bank is planning to ban access to Bitcoin exchange websites, it was announced by Sergei Shvetsov, the first deputy governor at the Russian central bank. This announcement had a severe effect on the Bitcoin price that was rallying towards $5,000. In a flash crash, Bitcoin’s value dropped by $600 before rebounding somewhat.'
• 2017-10-10: 4 Things That Can Push Bitcoin Price to $5,000 and Beyond • The return of the buzz; Financial crisis; Wall Street stamp of approval; Free money ('At the end of October there is another fork coming to Bitcoin in the form of Bitcoin Gold').
• 2017-10-29: Price Analysis, October 28: Bitcoin, Ethereum, Bitcoin Cash, Ripple, Litecoin • 'The number of hedge funds which exclusively trade digital currencies has grown to 120, with about $2.3 bln in total assets under management, according to the financial research firm Autonomous Next.'

Most of the BPA articles were of the type in that last bullet. They show short-term charts of each of the mentioned cryptocurrencies, along with a technical analysis of the price action (resistance & support levels, that sort of thing) indicated by the charts. I don't recall ever seeing anything like a fundamental analysis and don't know if it's even possible. Is the price of bitcoin++ driven entirely by market psychology?
