Airdrop starts: 12/06/2019 Total value: n/a Platform: ETH Ticker: MWC Total Supply: 20,000,000 MWC https://www.mwc.mw/

Step-by-Step Guide: Visit their official airdrop registration page. Submit your Bitcoin wallet address in which you hold your BTC and click on “register/verify”. Sign the message from the claiming tool using the “Sign Message” feature within your wallet (instructions for Trezor users / instructions for Electrum users) and paste the provided signature to prove ownership of your BTC address. You should never enter your private keys into any third party software! Once it’s done you will receive a “success” message and a password. Remember the password along with your BTC address, as it will be needed to claim the airdrop later. Snapshot for the airdrop will be on July 19th, 2019. Make sure to hold your BTC in the registered wallet address during the snapshot date. You must ensure to maintain access to the wallet/address you registered with, because you need to sign another message again after mainnet launch in order to claim your MWC coins.
