I don't mean multiple assets but the currecy used, on the Accounts.csv we can only set one currency that can be used BTC.B8, my goal is to use multiple currency where I can buy using BTC or XRP or USDT as base currency. So for example I use all my BTC to buy XRP then I want to use the XRP to buy other altcoin and so one and not only use BTC as base currency.
