Although I messed up and clicked the wrong link, byteball does have a faucet like tool on telegram that should deliver enough bytes to your private wallet to do the attestation thing. It gave me about 146k bytes.
After you are done about 20 multiple choice questions, you'll get a link with about 12 words. copy the 12 words on the webpage, go back to your wallet and then when you click receive, choose received by textcoin, and paste the 12 words.
Yeah, even I forgot about it that Quiz bot, but I guess referring other people creates bigger viral effect. I am currently writing a blog post about all the different ways how to do the attestation without asking somebody to fund the address, hopefully I will be able to post it soon.
Here, fixed it, added 2 more options how to do the Steem attestation without asking the fee from someone.
