I try to find the bounty ocampaigns on the forum or on the bountyhive platform, because it seems to me that there is the least amount of scam ..
Bountyhive is the platform where you find the place to good place to get the best bounties which rock in the market. I see the manager and find the good bounty in their aspects bro. Because I believe the campaign manager can pick the right project for their safety.
If you want to invest on the ICO project that time you can go ahead to read the whitepaper first and then confirm will it work or not mate.
