Is it possible to transfer LTBC assets to here for trading? how can I open a LTBC wallet?
If you’re asking about trading on the DEx: I think LTBC wallet can send so you create a wallet in Counterwallet and send coins from LTBC wallet to the address in Counterwallet. You may need to send some BTC to this wallet as well, because you need them to transact on the DEx (each offer/bid is a bitcoin transaction and eventually you’ll need to send the stuff out, so 0.0006 BTC should suffice for 2 trades and one “send”.
You can open a test wallet to play with the DEx.
