May look stupid to you.. but, once again, can we agree about what needs to be done to participate in airdrop?!

I have some HUSH on Cryptopia

Questions:
1. To participate in airdrop I have to transfer to my tAddress which I can create in HUSH Wallet, right? (Avoiding using default "bug" tAddress in wallet?)
2. After the time defined for "snapshot", can we bring our coins back to exchange or should we wait for airdrop to finish?
3. How we will get BTCH - by importing HUSH wallet.dat to new BTCH wallet or?

Sorry if it seems to simple to you, but just want to clear it...
