With under ten total votes

No.

I don't see the logic behind BTT, BCT seems more reasonable.
I always use BTCT. Why? Because it's BitcoinTalk, BTC + T == BTCT.
This is also a good abbreviation.
Besides, a poll won't give you accurate results at all. I've been telling this to people for quite some time now. There are too many shills and manipulators because of which it is hard to get accurate results.
