Spot margin trading

Because of tax regulations in Austria (and I think some other EU countries too) spot margin trading is a must. Trading futures or any derivatives creates taxable events in Austria but spot trading crypto to crypto (so not using fiat, only stablecoins) will not create taxable events. That's why I personally need to be able to trade spot and go long AND short if needed. If this feature isn't implemented it would be a deal breaker for me unfortunately.
