Kickstarter and Indiegogo are home to some of the most innovative tech ideas around, and theres plenty of choices if youre looking to invest in something cool, useful, or cutting-edge. Just before you part with your hard-earned cash, though, weve got some warning signs and red flags to help you tell the difference between a viable proposition and something thats likely to crash and burn.

That crashing and burning does happen: In fact, we even declared a (long-since lifted) moratorium on covering Kickstarters at one stage. Big dreams dont always turn into big products, and the most recent crowdfunded project to bite the dust was the Blocks smartwatch, with no product shipped in five years.
