Both the terms confuses me a lot. I mean I have started to feel that I am in both of them according to what I am holding and what are the characters of my coins really. Well nonthless smart money must be the priority but in many instances I have seen that dumb money where according to this definition is buy and sell of big chunks you say. I do that very often, for example cheap coins like IOST, scl, TRON, TRX and much more can get me into it. They are cheap and that's why buying them in bulk and selling them with average price rise can benefit a lot.

Now here is the contradiction : The dumb money could actually be smart one too if you do it right.
