I think there has to be a fine balance, never say never but with the current trends and plethora of project it makes sense to see some evidence that the team has the capability to deliver what has been promised at least a test alpha of a product. There are ICOs as well that uses the investments just to stsrt their company or whatever project they have, which is a good thing. Existing platforms that created coins for their products are the best of course, but others can be useful as well. Just research on the stuff the you need to before investing on anything.
