Firstly, rightBTC is really suc*s since they will fail your KYC for level 2. I've deposited some of my altcoins and did trading and then I tried to withdraw my funds but I didn't realize that they have a required KYC which is really annoying since they will just fail your application even though I provide all of my personal information.
And from now on, I will avoid this exchange and doesn't recommend.
By the way, I'm still waiting for my KYC application for the 2nd time.
