Are you using Steem right now? Engaged in the community? Talking and sharing content with others...
There's all the proof you need. Steem is legit for the utility of it. Same with ETH. NEO I'm not too familiar with but everyone seems to love it.

What our day to day activities are reveal the products we use. Excellent insight into product use and profitability.
