I'm pretty intrigued in the OpenLedger project, but I'm having a bit of trouble differentiating between the potential investment value of these three currencies, especially because OpenLedger itself is built on BitShares. And I'm not exactly clear how OBITS works -- it doesn't seem like a currency or a store of value.

However, the technology/ideas behind these innovations interest me, so I'm interested in hearing why you did or didn't invest in any of them.

I'm interested in investing in a coin that could serve as e-cash. In my opinion, Bitcoin is more like digital gold and Ethereum is more like an application platform. It wouldn't make sense for millions of people worldwide to make daily transactions with them (buying coffee for example).

I'm for the most part interested in PoS models of consensus because I don't think PoW is scalable worldwide -- it's far too energy inefficient (unless we have a surplus of energy from renewables but that's a long way away).
