As a newbie that does not understand the satoshi ratios and such but wants to get this coin it is not very easy.
Sure I have heard buy bitcoin, (already did this but takes nearly a week to show up in Coinbase), then exhange it (volumes and prices asked seem crazy). I would love nothing more than to purchase coins with USD, I believe any views of the upcoming fight are going to feel the same way.
As of now it is just to difficult for the average user like me to actually get into this coin without jumping through a lot of hoops, which starts to throw interests off.
I completely get that. I was terrified when I started trading altcoins (other coins than Bitcoin) as it can be a little tricky. The easiest thing to do right now is to transfer your Bitcoins to a good exchange like Mintpal, and buy Nautiluscoin there.
Basically 1 satoshi is the smallest divisible number of a Bitcoin, or 0.00000001 Bitcoins
So when we say that one Nautiluscoin is worth 20,000 satoshi it means that it's worth the equivalent of 0,0002 Bitcoins, or about 12 cents.
As for easier methods of purchasing,
www.Moolah.io is about to launch a platform that will allow people to purchase Nautiluscoin directly with dollars and euros. This will hopefully go a long way of making non-techies more comfortable. I'm not sure when they're launching that however, but from what I can gather it seems like they might do it during the summer.
