Bitcoin Reading List, Part 3

These two posts have two prior Bitcoin reading lists.

The original Bitcoin Whitepaper, by Satoshi Nakamoto, is a short read.

This is a good podcast to learn more about wallets and specifically the beginner-friendly Exodus wallet.

Ethereum Mining Backup

With the size of the Ethereum block chain always increasing, it is important to occasionally back up your copy of the ledger. In case your PC crashes, you will not have to start downloading the block chain from block zero.

Shut down any running geth processes


Make a backup of your keystore:
C:\Desktop>copy %APPDATA%\Ethereum\keystore\* .
C:\AppData\Roaming\Ethereum\keystore\UTC--2017-blah-blah-9
1 file(s) copied.


Mentally make a backup of the password for your keystore.


Back up the downloaded Ethereum blockchain:
