Without an easy way to buy STEEM with fiat currency, how can it rise above the pack?

It is fairly common knowledge, that the compared value of STEEM against fiat currency, parallels with the value of Bitcoin, Ethereum along with most other cryptocurrencies. They rise and fall, together.

Being that STEEM is an alt-coin, this is, of course, to be expected. In order to actually buy STEEM, one must first purchase one of the larger, main-coins, (I.E. Bitcoin, Ethereum, Litecoin, ect.) If I am incorrect about this, please let me know.

I am writing this post, because I want STEEM to succeed and I have not seen much posted on the topic of making it possible to purchase STEEM via fiat, with ease.

Paired with mass adoption, proper strategy in STEEM burning, and inflation, wouldn't giving STEEM stand-alone capabilities by developing an easy way to buy the coins for fiat, be something to shoot for? Although, I am fairly new to these concepts, I think I have, at least, a slight idea of the mechanics of these strategies. If I am out of my mind, please let me know. I have seen the proposal for developing a well interfaced STEEM marketplace, and of course SMT's will add tons of valid liquidity to STEEM, but is it possible for an alt-coin to graduate to the status of a main-coin, through fiat sales? I think I may be missing some information, so any help in understanding this, is very welcome in the comments.

*Just some thoughts, but if this is actually a good idea, it would be cool to see a team form to develop a fiat exchange. I wish that I had the technical knowledge to do that kind of work, but I do not yet possess it. I do, however, plan to eventually learn. I am planning to learn to code, after further research into some online tech schools.

P.S. Would be cool if it was a part of the STEEM interface, or even to set up an OTC link or section to be added to STEEM or some of it's front ends.

Feedback WELCOME!
