whats the chance this airdrop is a scam to collect signed info, for some sort of hack....i know ecsda still protects your BTC, but still.....

you lose the SHA256, and RIPEMD160 protections for that address, now only having  ECDSA.

There must always be a risk for any action.....

sure you could move your coins just before and after the snap shot, but  I would expect they are ready for that.

Also who really wants to crack open cold storage? Then have to move that all around....
