That being said, you can trust a company like Canaan much more than a brand-new start-up to actually deliver and send you your 'reward'.
Totally agree.
I only mentioned that the crowdfunding site was viable, because they questioned whether the site was viable to use. And in this the website itself is viable. What may not be the case is that the projects that are placed there are the responsibility of those who place them there. I've seen companies like Philips use this site for projects.
In this case, it is up to the user to evaluate the project and who is involved in it, to make their investment or not.
