We know that holding Bitcoin is better when users have full control over their funds. What makes an open source software better? Is there any advantage on using it than using close source wallet.
imagine a situation whereby you open a wallet and it has automatically created payment addresses for you to receive funds.
how would you know that the code behind it is simply a list of made addresses by the developers that have a copy of the keys.
in closed source wallets you wont know.
......until one day your funds go missing.
in open source you can check the code and see if the address generation is genuinely random, created from within the software locally on only your computer, to a high standard that in a billion years of maybe creating 1000 keypairs a second no 2 addresses would be the same.
