i think signature campaign is still the best option in the bounty to the present. but social media starts promising, too. There is even a campaign that makes social media campaigns for earning higher current and I would also advise you to participate in this company Sparkster ICO Bounty
I've heard about this project before! But did not give the value! Me seems complex platform! What conditions does this project require for the company to sign? If you can explain please! I will be very grateful!
