Well there seems to be no choice for those people that are hoping to earn big amount without doing some effort of investing. Though the price may seemed to be low now but it doesn't matter because it will pump again and I'm pretty sure about that. If he manage to do trading or joining some campaigns he can start his trading career already.
We cannot expect very high incentives from signature campaign as the income from it is very limited and low too but if he can save that income regularly then it can help him in reaching to a descent capital in future which he can utilize in trading and can become a full time trader and start making money out of it.
Yes we know that and even you are going to add some other giveaways and social media campaigns it is not really going to be enough. But it is better to had than nothing. That's why I'm trying to point out that he can use those profit for starting to trade with alt coins.
