NANO is reloading right now. Given the parabolic trend bending momentum behind this coin at the moment, I don't see it dipping very far. Would pick it up when it drop below the green line and wait a bit to ride the wave up again.
In case it drop below the purple line, it maybe possible drop it and pick it back again at Fibonacci 50 which is 9548 Satoshi. However, I don't expect this scenario to happen.
