The owner of Sittingbags is a friend of mine;
With litepaid you can accept 20+ coins and that is the beauty of it. For a webshop it does not matter what coin is used. But, to support the Guldencoin, he placed the image 'pay with guldencoin' in the footer and the Guldencoin is named as first in the sentence 'betaal met Guldencoin, Bitcoin of andere altcoins via Litepaid.com.'
In Dutch we would say: Twee vliegen slaan met 1 klap. (Hitting two flies with one stroke). I'ts better to accept all coins then just the NLG, but NLG gets the support, not bitcoin or any other.
