I think you are fine for now as it is likely going to keep climbing until the ICO. If you are risk averse you should probably look for an opportunity to exit at a higher price before the ICO as you may not get assigned in the first (or indeed even second) rounds, or if you are feeling bold take a risk and try to get it converted to IGNIS in the first round. You may also want to consider converting some of it to ARDR tokens in the coming days if the price of ARDR gets much lower than where it is now compared to NXT.
