As the owner of
www.bahtcoin.com I feel obliged to drop my 5 cents into the discussion. There is no
BTC sign in the website at all. And not for the reason to avoid confusions. We are here in Thailand do not use this sign in everyday life. It can be seen as a decorative or idiomatic element on billboards or signage, but in everyday life texts, price tags -- none. Or extremely rare.
Those signs are merely convenient and used in the environment where several units involved (dollar, cent, pound, shilling, guinea). Or maybe in third world countries where many currencies rotated simultaneously. Thailand is neither of them. It is has stable local currency and units are small (1 Baht ~ 1/30 US dollar) to avoid operations in fraction units (though formally it exists 1 Baht = 100 Satang). So whatever money amount written always means Thai Baht by default.
So I bless you to use whatever sign you like even
BTC. No big deal. It won't be any confusion anyway. And when you use really many currencies (particulary in Bitcoin context) you may see that not all of them has distinctive signs. Even large ones like Russian Ruble, Chinese Yuan. Imagine how odd they would look in such list for instance:
www.centraw.com/?page=rates You will have to avoid using signs for the sake of uniformity. Three-letter codes are absolutely fine in all cases and well cosmopolitan.
