And since I do web design and graphics art work, and was looking all this up (I found it fascinating) anyway, I figured I could make a guide that new people could use to understand cryptos better.
I apologize for this moment of brutal honesty, please interpret it in good spirits and solidarity.
I don't know whether to congratulate or criticize your efforts as you have created a site so monumentally ugly that it is paradoxically beautiful as it illicits a sense of nostalgia to an earlier time.
I was reminded of this treasure from back in the day when I clicked on your link:
http://www.pixyland.org/peterpan/Ouch...lol. Thanks for your brutal honesty. I wanted critiques with the feedback, and although it stings, I really appreciate it. Here's the thing: members here are not really my target audience. Forumers tend to be young, snarky, a bit jaded, with a (perhaps) exaggerated sense of self - import. You/they probably favor the most modern looking, lights and sirens type glitterazzi that is found in abundance on the various faucet/gambling websites.
I was striving to reach newbies, perhaps a bit older, a bit more traditional leaning, and maybe a bit more in step with a design and layout that I've featured here. I believe that as they approach my website, with a sense of curiosity and skepticism, the bells and whistles style might just deter them, and scare them off. After all, cryptos are not widely known, and/or accepted by mainstream society.
So while your unvarnished critique hits a creative nerve...in a way, it confirms that I've perhaps struck the right ambiance for my target visitor....if that makes any sense.
Again, thanks a lot for taking the time to check out the site, and post here. It is appreciated.
cryptocurrencies is the umbrella term for all cryptographic based currencies, thus including bitcoin.
then beneath that it separates into bitcoin litecoin and namecoin (the three main first gen) and altcoins, where most the other cheap pump and dump altcoins exist which have atleast 50% code copied from the first gen.
be aware that things like ripple, is not in the cryptocurrency category at all as its just a mysql database. just like facebook credits, world of warcraft gold, applepay, paypal. these are all part of their own categories
and then... digital currency encapsulates them all..
so going from biggest embrella to lowest entity it should look like this

Thank you for that terse, concise, and informative hierarchy. It is appreciated, especially since I am quite new to the digital currencies world myself.
