Only 5% over the last 24 hours. Now the ICO is in its last 20% (no bonus) so it will loose some tracktion and i can imagine that it will take at least a week to end. But lets see.
It has been slower down in comparison to first 24 hours but still time to time it picks up pace. I don't think it will continue another 2 weeks. It is matter of some big transactions and we are going to see it ending. Even with current trend it should reach to maximum cap in 3-4 days maximum.
