thank you for sharing this information.
I read this:
"Please note, the current version of the rewards portal has full support for Metamask withdrawals (which supports ERC20 compatible wallets and wallets created in MEW) but not hardware wallets such as Ledger or Trezor. Ledger support will be added within 10 business days and other wallets, over the course of the next 3 months."

I use my myetherwallet's private key with a trezor hardware wallet.
I don't understand...if i wait to the trezor support, i will lose first dividends airdrop?
