Yes, bounty is very profitable because i have already earned through it and what's very more interesting about bounty is that you do not need any money out from your pocket. Some people here even claimed they became millionaire of a single bounty only.
Yeah I agree with you but the earnings of a bounty participants will depends on their forum rank as those at Sr. Member above can get a higher stakes if participating signature campaign. For me even at lower rank it can still profitable if we don't sell our token at below ICO price.
