I don't think these 6 ways are really that helpful anymore except Airdrop and bounties. Faucet is not that popular anymore because, after a hardwork, you will get a tiny reward. Steemit is very difficult for newbies and without paying a buck, your career won't be a success there. Crowdfunding, I mean your platform is not that worthy to me. Only Airdrop and bounties are the best way to earn crypto token without investing!
