the transparency in all our transactions including our crypto purchases and other crypto trading activities, and of course the ease by which we can trade in almost any currencies that we need to do so (e.g. GBP Pound).
The only down side I have with Tzero right now (which is minor) is when it comes to buying ETH or XRP directly from their platform as you are often given too many choices at once and this does take time plus a lot of choice just confuses your mind into making wrong decisions. For us traders at tZero who use it actively it's been great but for those who aren't active users sometimes they end up missing out opportunities because there isn;t enough liquidity to match what is available off exchanges like Kraken/Poloniex (we try never miss an opportunity where it comes!) If you're thinking about getting it yourself then maybe get one user I was able to find an investor with whom we could have conversations about our business model/idea without having them sign any NDA's or anything like that! While it can be hard finding investors who are willing-to -pay cash (which this one did), they were very open minded when looking at how their money would get deployed in my startup idea so there wasn't much friction between us during these discussions either way!!
