So there's this campaign that I've participated that locked bounty rewards in the hopes of avoiding token dumping. As what I expected, the dumping still happened. What's even funnier is that it is now the bounty hunters who complains unlike before where investors blame bounty hunters

If there's any coins or tokens that should be locked, it should only be the team's share (or maybe add those given to advisors). Both parties (investors & hunters) have invested either money or time to get their share and they should not be subjected to such restriction.
Instead of locking, teams should just concentrate on other methods such as buy back and loyalty rewards to lessen the chances of price crash.
To link topics, IEOs also require locking of tokens post listing to mitigate the risk of dumping. Another benefit of the IEO, they are protecting investors and the company.
That sounds bullshit for me and why? have you seen veriblock IEO that has been hitting bottom price that makes a lot of investors are getting looses? I hope you can see that and you can change your mind about IEO. not all IEOs are good for me personally.
Your right, but you have to remember investing comes with inherent risks and while not all IEOs will provide results, I think the framework of an IEO is a step in the right direction.
How is it a step in the right direction? Is it more transparent than an ICO? How many can participate? I'm talking about IEOs on bigger exchanges here.
I'm using the assumption that exchanges are doing their due diligence and investigating the projects they accept on their exchanges for IEO's.
If this is not accurate then we have a problem for sure, I guess stick to reputable exchanges (obviously) and time will tell if they have a greater success rate.
Investing is always risky and there are NEVER guaranteed returns, adding another layer to the legitimacy of a project is, in my opinion, a step in the right direction.
