In the present, during an era of ICO, there are no difficulties for start of the own project at all. The only thing that it is necessary for you, this huge number of money to employ in the team professionals, well and of course own idea.
Of course we would have something to do more seriously, such as to hold an ico, you need to have that just money, nothing. But what about the experience or at least small knowledge in this area and the idea. And I think mercenaries are now very much everywhere there.
The idea of the ico plays a prominent role amd on basing the infrastructure and team building in making all the project document procedures to let the team involve and ultimately deliver the expectations matters for the user to choose and hold the project.
