1) Allowed me to "store value" in a variety of different assets (USD, various US stocks, commodities, etc.) -- NOT a single speculative currency.
2) Anonymous/no transaction records
3) Multiple issuers and thus multiple roots of trust; If I had $100k to store offshore, it wouldn't all be at risk to one entity.
4) Protocol designed for anonymity; wallet software or wallet providers who left no particular trace on your local machine, network traffic monitorable from your local machine, etc.
In short, some kind of open network of blinded token issuers, NOT bitcoin.
