I created account was quite simple, then you need to log in. When I send funds was very fast. I use the buy order takes about 15 seconds total then you scroll down to see transaction go through.
Overall quite smooth for a testnet, transaction showed I did transaction of 250 and charged 5 for a buy order of 0.1 btc. I do more testing and see if there's more improvement !
Thank you for testing! We will let you know when the team makes some updates to keep testing.
