From where we were in 2017 the model has changed. IEOs/ICOs have reduced the opportunity to earn bounties....but that's also systematic of the difficult time crypto has had in the last two years. Should we find ourselves in a bull market again, and "alt season" really kick in....I'm sure we'll see bounties pick up again. Not sure they will ever reach the profitability heights of 2017, but don't see things getting much worse than they are now.
many new methods for collecting funds because in my opinion it is caused by the number of scammers who make investors disappointed so that they are currently collecting investor funds only from the safest methods such as IEO at a trusted exchange place because if using the ICO method investors are not trusting and not interested again.
