Blindly brushing aside criticism as "FUD" is not a good investment strategy. There are lots of technical concerns around IOTA and maybe they can overcome them, and maybe they can't. But the cryptocurrency community's response to criticism is largely sticking their fingers in their ears and decrying it as FUD. Let me be clear that naysaying all the time is not productive, but neither is uncritically accepting that the system is flawless.
