I am in complete agreement with you on this.
Steemit offers a unique opportunity since people can "invest" in Steem without buying in. Every other cryptocurrency that I know of requires one to buy in (unless you use a service to "earn" it). Brain power over money could be of interest to many people.
One point you missed, which I think has even greater potential is DTube. When you consider that Youtube is the #2 site in the world, that means there is a ton of potential in video. Dtube is built upon the Steem blockchain, offering another decentralized service.
There is a lot to be excited about. For those investing a little bit of money in, one could be looking at 100 times return in the next 5 years or so if Steemit (and the other associated sites) really takes off. Considering the traffic you mentioned is with less than 400K members, can you imagine what the traffic will be with 4M?
When you are looking at a risk reward scenario, this is a high upside with little downside.
@taskmaster4450 You're completely right! As an avid user of DTube, it's pretty weird I forgot to add it in!
I'm adding a section right now to the post titled "Building Decentralized Services on Steem." Take a look and see if you have any feedback.
Thanks for your comment :)
