I read the OP with the instructions on future distributions - so just to clarify.
I have GBytes currently held on an exchange and my BTC on a hardware wallet.
To participate - I just need to download one of the wallets and also the chat-bot and follow the instructions and that's it?
I would need to send a micropayment (or sign a message from my wallet) to the address specificed by the bot and also transfer my Gbytes from ex to wallet.
Is the signing of the message safter than sending a micropayment? And just to clarify - after we send the micropayment, we can send it back to our wallet right?
After this is all done - we just wait until the next round and the Gbytes and Blackbytes will be automatically airdropped to our wallet?
The micropayment isn't returned, better use message signature. For the rest you've well understood.
For security, I would advise to set-up a multidevice wallet with at least 2 cosigners required.
