Bounty campaigns are the best way to earn free tokens, 2nd option is air drop but they pay very less tokens. and most of airdrops dont give any coins. even though they give you coins these coins will never be listed on exchange. I think you better follow only bounty campaigns.
Also we can become investors if we buy their ICO. With what you have to say, here are the only two ways we can get the token without joining the bounty program.
But I have a question that the bounty program is the best place for him to own free token, but why he does not want to participate in it ?
