I can't create Asset with "dot" character

[trustpay]

I got it. Thank you!

I wonder how "RUDEX" and "RUDEX.GOLOS" are created by different users?

https://openledger.io/asset/RUDEX
https://openledger.io/asset/RUDEX.GOLOS

They belong to different users *now*. The issuer of an asset can be modified after it's been created.

because GOLOS is the main asset in RUDEX.GOLOS

edit: it's the other way!

[trustpay]

I tried to create UIA name "TRUSTCARD.USDT" on openledger.io but an error screen is shown:

Should I create the asset "TRUSTCARD" [...] before I create "TRUSTCARD.USDT"? (In case my username is "trustpay")

Yes. Only the owner of asset X can create assets X.Y.

I tried to create UIA name "TRUSTCARD.USDT" on openledger.io but an error screen is shown:

"Failed to broadcast the transaction

If I create the asset on bitshares.org/wallet, the error is

I don't know how to solve this problem. Should I create the asset "TRUSTCARD" or "TRUSTPAY" before I create "TRUSTCARD.USDT"? (In case my username is "trustpay")
