Not familiar with those but the general rule of thumb is, to improve and enhance our DYOR before engaging in something.

If you are an experienced lurker at those types of projects, somehow you will able to speculate if they can create a sort of hype. Generally, as we always witnessed in the altcoin world, remember that without hype, these types of projects won't last long even with how good the project concept is, in most cases.

It's not wrong to take part in those projects as long as you know what you are dealing with.
