I got the same error even after changing from Python 3 to Python 2

Did you install the requirements ?

Try using Python version 3

@meesvw $ ls Btcbf.py _config.yml requirements.txt README.md address.txt blink@localhost:/storage/emulated/0/Download/Btcbf-main$ python3 Btcbf.py Traceback (most recent call last): File "/sdcard/Download/Btcbf-main/Btcbf.py", line 3, in from bit.crypto import ECPrivateKey ImportError: cannot import name 'ECPrivateKey' from 'bit.crypto' (/home/blink/.local/lib/python3.9/site-packages/bit/crypto.py)

I don't recommend running this on an Android device, but if you really want to you could try this:

pip3 install -r requirements.txt

This command will install the requirements using python3.

Next rerun the script if you get no errors. This should solve that the requirements can't install. If you still get errors it's probably because arm isn't supported. If that's the case you can't run it...

[meesvw]

I also saw this in your error log: fatal error: ffi.h: No such file or directory

Which can be solved by installing this package: libffi-dev

Command sudo apt-get install libffi-dev

It is not recommended to run Btcbf on Android. To install the requirements, it is necessary to have cryptography libraries installed. On Android cryptography libs need to be compiled. It takes a long time and effort.
