I've seen flashcoin but I don't have an currently have an opinion on it. However there are some things to think on: 1) As the video said, altcoins are currently in a bubble. Therefore, unless bitcoin dies (which is not a zero chance) then the value of flashcoin, even if it stay up, is unlikely to skyrocket(low ROI). 2) is it the BEST? Can't answer, do some research. also, what are it's competitors? are they better? Make your decision. And 3rd) (medium to longterm question but relevant to # 1 is when will bitcoin lose top position(if it does)?

Not everything or even the majority but can be a good starting point.
