I think this project is amazing as well, and I really enjoy using it as my preferred method for coinjoin txs. However I do have one complaint. The other day I was using the sendpayment.py script. The command was exactly:

Code:

python sendpayment.py -C -N 4 0

The script put the transaction together, and presented me with the options and a "y/n" prompt. I pressed "y" without paying too much attention and ended up paying some asshole 2.8 BTC to send a little over 5. Which is more than half of the bitcoin controlled by my privkeys. Sad

A couple suggestions:

1. Kick those people from the IRC with 50%+ fees.

2. Present the cjfee in something other than satoshis or have an alert that says you're about to pay an insane amount.

Thanks for the feedback. Sorry for you loss.

I made this commit https://github.com/chris-belcher/joinmarket/commit/be8b63fa332d18a4ba71d68e3894d29d4c9db7c8
It displays the coinjoin fee as a percentage and prints out a huge warning banner if its above 2%

Code:

[2015/07/20 02:45:10] total coinjoin fee = 2.1%
