I know this is a pretty minor issue but I would prefer to resolve it.
I have seen people using both versions. I would prefer if we were consistent with the capitalization in all official material. For example, bytemaster uses BitAssets and BitUSD, BitGold, etc. in his blog. The BitShares client also uses the capital B format. But the bitshares.org website uses bitAssets, bitUSD, bitGold, etc. (although there are some places where the website mistakenly uses the capital B format).
Personally, I prefer BitAssets, but whichever way the consensus goes is fine with me. I just want consistency.
Which capitalization do you prefer?
