Purchasing BYDDY via OTC on Stake

Just wondering, on Stake, the minimum is $1,000 right, so I’ll need to purchase $1,000 worth to get some BYD shares with them through OTC. Just wondering, with their minimum $1,000, is that US or AU?

I also can’t figure out the fee they will charge either - is it a % with Stake for an OTC? Or is it X amount per purchase?
