Just find out that in Talkcoin chat, if you click the "B" for bold text by mistake, then it will cost you 10 TAC instead of 1. Normal chat just 1 TAC. Find it the hard way....LOL. Stopped mining TAC after about 500 coins, it should cover the chatting for a while...
What become to the TAC we give when chatting ? Everybody chatting lose TACs so who is the big winner who receive all the TACs ?
