If crypti price drops lisk value will drop
I would suggest to do the calc without Crypti, because it's not possible to sell all those XCR - they have nearly no value.
if btc drops lisk value will drop.
Sure. Too early in the morning.

Thanks for the script!
You can't really do the calculations without Crypti since Lisk is offering an stable conversion rate of 0.000013 per Crypti. Those who are trading in Crypti will receive LISK in exchange, even though it means Crypti might not be sold.
If you do the calculations without Crypti, the value of LISK will decrease and you will end up selling below the ICO price.
