Re: [ANN][LISK] Lisk | ICO | Decentralized Application & Sidechain Platform
For all price fanatics I have setup a simple price grabber that get's the ICO amout from ico.lisk.io and does the proper math to calculate the lisk price in satoshi and USD (bonus not included).
Okay, it does. Awesome API-magic. Could you please make the stuff public? Would like to change the formatting and design of this image.
P.S.: Why did the price fall from 2608 to 2584? Shouldn't it increase only?
If crypti price drops lisk value will drop, if btc drops lisk value will drop.
