Yes, 2018-2019 is a so bad time for bounty hunters and also for investors. There were too many scam ICO projects at that time. I still remember that I ever stopped working bounties for a while because of no earning at all. I am sure you also did the same as me, reducing the number of following bounties or even stopped temporarily. A better era of bounty just started after IEO became trending to replace ICO. Till now, most bounty hunters prefer to join bounties provided by IEO projects.
That's obvious, but when the IEO trend is running, there are also many scammers who take advantage of it by creating several IEO projects that are eventually listed on bad exchanges like P2PB2B, it also indicates that the scammers never stop setting traps for everyone people in the crypto space.
