I like Turtlecoin, i think your logo will create an awesome brand combined with the awesome tech under the hood. But hijacking "Cowabunga" from teenage mutant ninja turtles on your ann is just horrible branding imho.
That's like saying Dogecoin is unprofessional because it uses the doge meme. TRTL is supposed to be a fun crypto also, how could a fun saying like "cowabunga" hurt?
