Quality and fantastic Sabunir ! I really like them.
Suggestions:
(1) The background 'fade' effect somewhat detracts from the text in the smaller versions of the logo. Almost making it unreadable (tricky one as I realize it's taken from the website header)
(2) Maybe a mention of 'P2P'. Maybe not...
(3) Embossed blue / dark blue outline ?
I'd be happy to pay to use the logo's (I have already sent giik a token 100BTC donation)
