The product is important for the project, but in fact, there is now a market manipulation scheme, that is, whatever good product the coins will not grow or projects 
But at least a good product and it's ready to use (even though the beta version) provides a plus in investor valuation. This saturated market situation is less profitable, hopefully, it will improve soon so it can improve various conditions. So that a good project with products that can realistically reach the maximum price.
