i suggest you to join a telegram group with bounty campaign.
It takes only a second to shut down a channel if the owners decide to sell off the project/blanket scam the investors. Having a telegram channel is a mode of communication only. Not a sign of legitimacy. You can never know who the admins really were and/or legally pursue them if you are an investor.
Make sure the bounty manager is trusted and supportive , because he will make sure the bounty campaign is legit and paying.
That is the not the manager job. You are making a wrong over-simplification of terms. Manager only manages the campaign and get the data sheet out for the allotted payments of each member. They have not power if the owners decide to shut down the bounty.
When i choice bounty campaign it is better if the token or altcoins is already listed on any exchange.
Thats weird because most tokens are sold before they are released. If you refer to IEOs, then good luck selling them.
