This script calulates rpietila's trendline for any given date >= 2009-01. I hope it works as expected ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) Price for today: $ python -m btctrend 336.00Price for Christmas: $ python -m btctrend 2013-12-25 430.83Typical price 2014: $ python -m btctrend 2014 1605.46import argparse from calendar import monthrange from datetime import date, datetime

WHAT'S WITH THE REFUNDS?
+1

My SEPA just arrived. Can we have that 160 again, please?
Oh, and I think 200 will be tested again in the coming minutes...
FTFY

Some images of the board:
Very nice, pity about the commercial price of what once started as a great DIY project. +1

1. You convert existing orders that have not been refunded yet to Bitfury product orders. The 70% partial refund will be deducted from your final order price. 2. You choose to get the 50%, later hopefully 70% partial refund.
What's the difference between 1 and 2? my interpretation: 1 ← if you want hardware 2 ← if you want money

My chips are in batch 7. If one batch has 10k chips and one module has max. 20 chips and burnin produces 1000 modules per week, should I expect my modules ~4 weeks later?
Thanks for this great project!

I'm in the same boat, I ordered chips from zefir and now I'm waiting for burnin to start accepting orders. I think it would be great if burnin delivers in July. But I wonder how it is possible for one person to develop, test and deliver a mining board in just two months.

The Ripple network also works with Bitcoin IOUs. Since the Ripple network relies on ripples (XRP) for transactions they will exist as long as the Ripple network exists.
