Both are both a bad thing what only spoil ICO is the level at which fake projects are increasing daily just to run with people ethereum and bitcoin. If a project is outstanding and decide to do ICO it's not a crime. But ICD is risk free you only get the token or coin by doing specific tasks.
That's what i think too since ICD do not require you to invest with bitcoin or ethereum.
Is ICD really risk free in that regard? If you see an ICD and even if you do not understand what they are trying to solve... It seems like a good thing to get some, right?
