Dear Digital Gold - Welcome. To answer your questions:

What's next? The Team is building a bridge so BAY can start trading again.
BAY is unique in that it runs a dynamic "peg" to price itself, which is roughly equivalent to 1/100,000 the hightest ever value of BTC.
So in theory, each bay is currently roughly equivalent to .64cents (US); because BTC at it's highest point was approx. $64,000 US.

What are differences among BAYR, BAYF and BAYL?
Good Question. This has been asked and answered many, many times since BAY launched it's peg.
The very best answer can be found on the website.

Now a question or two for you, as I am interested to find out more about your ad project and its future:
1. How can Digital Gold insure that it actually has the physical gold to back up a coin? Can I go see it, and handle the gold with my name on it?
2. How can I be sure it hasn't been re-allocated 1,000 times?
2. And if you actually have some gold locked up somewhere; how can one be sure that when SHTF the people guarding the gold don't just walk off with it?
3. And finally, what do you say to people like me, who actually own a real gold mine in Alaska, when I state the age-old truism: "If you don't hold it, you don't own it"? Which is why investors in crypto should never, ever perminately leave their savings in someone else's exhange or wallet - a la Mt. Gox.
