Any alt coin (DASH) that needs to setup a booth at a conference to promote itself is a red flag.
You guys remember all of those litecoin booths at previous conferences??
Oh wait...
There were none.
What a Litecoin Booth would go like
"Tell me about Litecoin"
"It's Bitcoin, with 4x more coins and 4x faster blocks"
"Sweet, what else?"
"Uh that's pretty much it LOL, we own a ton"
Dash Booth?
"Tell me about Dash"
"Anonymity, Instant transactions, Incentivized Masternodes, Decentralized Governance by blockchain, Integrated solutions for scaling to Visa levels and much more in Dash Evolution"
