as in ordinary business, many campaigns close and new ones replace them. this is a common situation and each of us must be prepared for such events and be very adaptable
So projects are indirectly just using the industry as a money making machine to generate money and then go away, and what assurance do we even have that those project that has failed are not still the ones that are coming back again to raise money the second time.
If we needed to control these things, old project are the ones we are meant to even pay attention to so that any old dead project would not think of coming the second time through another name to generate fund all over gain which I think that it is the highest form of scam I would ever see. Most of these altcoins are just having repetition of products and that is why they are failing, no wonder Barndt said they would not extend more that the time they have spent now.
