Well. Logo discussed. Now we will start an abbreviation. The abbreviation of a coin consists of three letters TAC. Well it or is bad? If it is related to your mother-in-law, it makes no difference. If it is related to cryptocurrency seeking to gain the world recognition is causes a number of questions. When the unaware person sees these three letters that he has to think? What is it? Mint candy? Committee of technical assistance (UN)? Whether it is necessary to demand from it something bigger, except how to use search in Google? From this it is possible to draw a conclusion that in this word associative communications don't work. What is TAC? How these three letters express sense of the full name? If it was reduction of the long word or group of words, such option would be logical. But word Talkcoin not the long. Moreover, that its part which contains an essence of a coin consists of four letters. Talk as an abbreviation looks quite capaciously, expressively, specifically, informatively and self-sufficiently. This word will be sharply distinguished from hundred abbreviations of cryptocurrencies. Why? Because it not abstraction and the word from a lexicon. It is easily perceived as doesn't need decoding. The brain doesn't strain and doesn't process information. The word TALK as an abbreviation possesses force, ease, beauty and a positive. I consider that change of an abbreviation would serve promoting and strengthening of positions of a coin.
