BCT = BitCoinTalk
BTT = BiTcoinTalk
It's pretty obvious that the first one makes a lot more sense, right?
Another 'correct' one would be BTCT = BitcoinTalk = BTCTalk; but a 4-letter abbreviation doesn't sound/look as good.
My thinking 100%
I have only recently seen people refer to the forum abbreviation as BTT
I dont know any other abbreviation where the first and last letter of the first word is used,
an abbreviation is almost always the first letter of each word.
SO while B and C are not exactly correct because we use Bitcoin as a single word but technically
there are 3 words in the forum name
Bit - as in cryptography [SHA-256 bit encryption]
Coin - In relation to a currency or something transferrable from one person to another
Talk - talk and discussion around Bitcoin
I'm not very technical but its prtetty obvious why the abbreviation is BCT
otherwise BTT should actually be replaced with BT CN TK
