Why don't you add a place that show how much BTC/ETH is collected to the progress bar?
Right now statistics:
654404 PKC SOLD
15 BACKERS
Current bonus: 10%
Current rate: 1 XBT = 6000 PKC
XBT means Bitcoin, right?
Yes xbt means bitcoin according to them, you also made a valid point, putting how much BTC and ETH raised would show transparency and honesty to encourage more investors.
