My thoughts:
Logo 1 is tricky. As a corporate logo, designwise, it is more sophisticated. Initially it confuses you, what is that shadow for?.. and then it hits you, It's K and C .. and then it turns into an optical illusion because it shifts between K-C and I-C. You have to dig deep down and once it settles in -----> Kobocoin = International/Internet Coin/Currency). I am not sure if that is what the designer was aiming for, but that is how I interpreted the logo.
Logo 2.. it's simple and direct to point.. Kobocoin is a currency.. and then the image of a flying bird/plane swoops in, it's fast. It doesn't hurt that it looks like a green and K version of the Bitcoin logo. Another point, when I asked my 6-year old daughter which logo she prefers, she pointed to Logo 2, because it looks like a money. If a 6-year old can get it .....
If we are targetting for broader consumer adoption, I am voting for Logo 2
