Ok, so I got my 50K coins from the giveaway, now what? I thought they had a community that I could lend to and be paid back (idk if with interest or not, can someone shed light on this?) and earn security points or whatever so that people knew I wasnt a scammer, but from looking at the website, it doesnt seem like there is any place to do this. So what can be done with them?
The point of the giveaways is to allow you to create an account, fund transactions, and test the system to see how it works. Real world applications are still pretty limited but, hopefully, growing rapidly.
We're promoting Ripple as a payment system like PayPal or mailing someone a check. Using it for community/personal credit is possible, but not likely to be significantly useful in the real world for awhile.
While we are working on eliminating a few of the step, the basic way you use it now is like this:
1) You create a Ripple account.
2) You open an account at a gateway (currently WeExchange or BitStamp).
3) You configure your Ripple account to trust the gateway to hold some amount of money for you in some denomination.
3) You deposit funds of some sort with the gateway. They could mean you send them Bitcoins, dollars, or any other currency.
4) You "withdraw" the funds from your gateway account to your Ripple account. You now hold "IOUs" from the gateway in the Ripple system. This works much like a bank balance -- if you have $50 in the bank, that means the bank owes you $50.
5) You can now send and receive money by exchanging your IOUs on the Ripple system with anyone who is willing to take them. You can exchange currencies, switch to IOUs from a different gateway (if that's what you need to pay someone, for example).
6) When someone pays you $50, they do it by making your gateway owe you $50 more. When you pay someone $50, you basically make your gateway owe you $50 less and their gateway owe them $50 more. If you trade USD for Bitcoins, you wind up with your gateway owing you Bitcoins on the Ripple network.
7) If at some point you want to get some of these currencies out of Ripple, you command your Ripple account to withdraw them into your gateway account.
8 ) You can withdraw funds from your gateway account using any withdrawal method the gateway supports. For Bitcoins, for example, they'll transfer them to any Bitcoin address you specify.
This is exactly how exchanges work now. You deposit USD at an exchange and have USD in your exchange account. For the exchange itself, you and someone else swap exchange IOUs so that the exchange now owes you Bitcoins instead of USD. You then withdraw the Bitcoins from the exchange account. Same thing, though there are a few extra steps right now.
The basic idea is that because some people have withdraw on demand agreements with a gateway, they'll value those IOUs at very close to face value. That will make everyone value those IOUs at close to face value.
