Having a good working product is definitely important, for one it brings more trust towards the project itself. Members will feel more comfortable with investing in a project that has an physical product. If a working product is not available, then a prototype or a demo is needed that will show how the actual product will work.
I think so, in every business venture the product is always the key to a sale. In crypto projects it may be in a form
of a service or anything but the main thing is that you need to have one in order to get into the market. The company
or business is only as good, as solid and as important as the product and service it delivers. That is the primary basis
to start and get into the big game. The next is the marketing and technology applied, lastly the maintenance and
further developments to be offered.
