"Obtain the private keys for your address(es) using `dumpprivkey `"
What if my tokens are in desktop wallet?
Also that part looks strange to me - I will NEVER put my Private Keys anywhere so should you.
As seen in many different Coins, Airdrops do not need privat keys....
You'll get the airdrop into any NEBL wallet, however Orion is the only wallet that can handle NTP1 tokens at the moment -- and that is why you have to sweep them in in order to use them. You're also welcome to keep the NTP1 tokens tied to your other desktop wallet, however you will not be able to see them until a NTP1-enabled desktop wallet is released.
in what proportions will be?
