Second, what is my public address. The main front of the client shows me one that starts with xrb_ and below one that starts with m1h. Is this public and private key? Third, how can I backup my wallet so that I can restore it when the software is deinstalled and the keys are unaccidently lost?
It is not that easy to buy Raiblocks yet. Only on BitGrail and Mercatox right now. Not pretty famous exchanges. Is it planned to list it on one of the major exchanges?
I think it's a single address but you might be confused because wallet splits it in two lines. And there is an option to backup wallet seed in Advanced > Accounts
