kandi X-RAY | cryptocurrency-analysis Summary
Having followed the cryptocurrency market for a while now, I decided to do some exploring in the data available from coinmarketcap. Especially in light of the increasing number of successful coins and decreasing Bitcoin dominance in terms of market capitalisation, I assume many investors are eager to understand the dynamics in this market. To replicate, first head over to coinmarketcap-scraper; this lets you download data from coinmarketcap into a local database. The script analysis.R can then be run on this database - copy the database file to your R working directory.

QUESTION
Im trying to import 100 CSV files from this kaggle link - https://www.kaggle.com/natehenderson/nate-s-cryptocurrency-analysis/data
Each file contains the historical information for a different crypto currency.
Each file looks like this:
for the current analysis I only need the Market Cap Column of each of the files along with the index which is a time stamp.
So for each file the only column needed is the Market Cap. Then I need to append each column & replace the name of the column with the name of the file.
The final result should look like this :
Where each column contains the Market Cap & of coarse each value should correspond with the index, and the name of the column should be the same as the name of the csv file.
any ideas how I can do this?

QUESTION
Could someone help me with decoding this error message for my Spyder console in Python? This likely relates to the fact that whenever I updated my Anaconda package from 3 to 3.5, I saved it in another new folder. After I realized my mistake, I uninstalled and deleted the former Anaconda navigator. The environment it is referring to is one that I created but never really used, so I'm kind of confused why it was selected as the only available environment for my updated version. Here is the error:

pkg_resources.ContextualVersionConflict: (parso 0.1.1 (c:\users\mlt08\anaconda3_5\envs\cryptocurrency-analysis\lib\site-packages), Requirement.parse('parso==0.1.0'), {'jedi'})
The error message is quite clear: you need to downgrade the package called parso
to its 0.1.0
version. If you are using Anaconda, you need to open a system terminal (i.e. cmd.exe) and run there
conda install parso=0.1.0
If that fails or you used pip to install packages in your environment, then you need to run
pip install parso==0.1.0
Note: For next time, please try to report Spyder errors on Github instead of opening a question here. This exact same error has been reported a lot of times already.
