I am unfamiliar with that one. iTrust Capital is looking to become the CoinBase like tool for IRA's, but to date is limited to just 11 coins, and no easy way to rank and stack like CoinBase.
Actually, in my kids IRA's, I have been using what I call a flip-flop chart that compares Bitcoin against Ethereum with good results. I am using the Grayscale ETF's GBTC and ETHE.
