It's a great idea, as I do worry about the price of HBD if the dollar is being inflated.

However I would suggest you talk to the Hive Engine ppl about what it will take to maintain the peg, if someone tries to manipulate the price. You'll need a lot of liquidity to prevent it from getting de-pegged like USDT was, and getting rekt. Keep in mind that someone has been manipulating BEE, and through that has also attacked a few other Hive Engine coins on the market.

So I would suggest to do a lot of research into how to stabilize a peg, and prevent it from going into a death spiral. If you can find a way to actually back it with silver, I think this could be revolutionary! Maybe talk to the silver community, and find a way to work together with them. Something that somehow compensates them for backing the token with their silver, and provides a safe haven for those worried about inflation.

However it has to be done correctly, or it will fail, and hurt a lot of ppl. It's not going to be easy to do this correctly, but I am not discouraging you! I am just also on this same learning journey with creating a token for SkateHive, and have learned some hard truths along the way.

Best of luck, I hope you succeed!
