18 days is still a long time, anything can happen, 100% threshold can be met now if today LSK price jump to 0.0003121
The other possibility is lisk huge pump to make the average price higher to reach 2000 BTC, but it is unrealistic, raise as more as possible coins is the most important thing.
No pain no gain, I may think the big chance for ARK will reach their minimum requirement if the last time of the ico they made something is big for hitting the big hype.
