I am on the verge of launching my ICO and want to buy a bitcointalk Hero Member account.
Is there any place where these accounts are sold?
Also I want to run a signature campaign. Kindly someone explain to me what a signature campaign is and how to run it?
If you want to launch your ICO you don't need to buy higher rank account, because you all you need is to hired trusted manager. Also you can open your own signature campaign but make sure that trusted person our holding your fund. Therefore try to consult some DT members to give you some advise regarding launching ICO and signature campaign.
I don't see the need to buy a hero account. You just need to hire a professional Manager to manage your company. You can write PM for example yahoo62278. This is one of the best managers on the forum.
I highly recommend Yahoo62278, but there's a lot of managers are launching signature campaign so its depend to the owner of ICO if who's manager or trusted person they select.
