Nice thoguhts and effort put into post. But lets be realistic. Althrough steem gives you free money and account at start with 6$ value ATM, and its easier to get in and use.
How much vaue is in it?
I'm sure people will come to platform at exponential rise rate for some time, since all people that are into cryptocurrency will come and all of those that will see this as the train to come to it easilly .I'm sure community will have major benefits from that.
But naming your blog and those point you put in blog that is killer app is just over the point IMHO.
Lets hope this strenhgten this community of crypto, and educate people in better ways for using it not killing Bitcoin or thing you mentioned in title post, becuse all that 99% of major population knows about crytpocoins is that Bitcoin exists. Killing BTC would be killing steem as well.
Variety of crypt just helps it and one or two strong ones makes it just like modern corporate world.
Please be sensitive with your title names and be real, focused on quality that you own and not clickbait.
Best regards.
